I found what can cause the Avast forum login to fail to work for
ALL browsers (for those that have found they were unable to login to the Avast forum). If you use a different email address for logging into the Avast Account (my.avast.com) than you have for the Avast forum then you won't be logged into the forum (OK, makes sense so far), but what this also does is make the "login" button in the Avast forum totally non-functional (Oops, doesn't make sense).
This is because Avast has linked the forum login to the Avast account login (my.avast.com), so then why have a login link in the Avast forum at all? That is, since the user is either automatically successfully logged into the Avast forum when they login to their Avast Account using their "matching" Avast Account login ID or is not successfully logged into the Avast forum in the event the Avast Account (my.avast.com) login does not "match" the Avast login ID on file and there's nothing else to be done either way. On the other hand, if the user finds they are not logged into the Avast forum account one would still in this case not expect the login link that displays on the Avast forum interface to basically be totally non-functional and simply do absolutely nothing which is what happens in this case. It seems to me that the login button in the Avast forum has become perhaps confusing, redundant and clearly sketchy because all it does now is trigger the login to the Avast Account (my.avast.com) interface. And if the user logs into an Avast account that is not linked to the users forum account then the login link still remains displayed in the Avast forum (because the user is NOT logged into the forum in this case) but is currently a totally non-functional button at that point.
Epiphany, if the "Login Button" doesn't work in these cases then how about providing the user with an explanation as to why it doesn't work? How about prompt the user they must login using the same ID and PWD as they currently have for the Avast Account?.... Uh, hmmm, but wait... in the case of a new Avast Account ID this would not actually exist for the Avast forum.... hmmm, it appears a Catch-22 is developing here apparently because if we create an Avast forum ID to match the new Avast Account ID then oops we have no more past Avast forum user history obviously.
So then we're stuck with having to renew an account to the same email account ID that needs to match the Avast Forum email ID that in some cases might involve an email address that no longer exists at the present time. Epiphany once again, Houston we've got a problem..... Great!!!! If I'm not mistaken it appears we've unfortunately reached an impasse that Avast apparently did not take the time to think out.
Avast needs to in my view take a different approach. Avast is expecting people to always be able to keep the same email address for the renewal (in order to sync the Avast forum for that user). I've now actually found that up to now I've personally got 3 different Avast accounts all with different information because I've renewed under 3 different email addresses over the past 15+ years using Avast.
The problem is that with this new "single-sign-on" approach the Avast forum is now linked to the email address of just ONE of those Avast account email address ID's. And if you either don't recall the email address ID previously used or are unable to login to the email address ID that exists for your Avast forum (because it maybe that the former email address may no longer exist) then you've got problems.So what happens if a person no longer uses a previously used email address? Avast, did you think of that possibility? Does the user in this case lose their entire Avast forum history? I presume then a user has to go to the trouble of having Avast transfer all of the Avast forum account information over to the new Avast Account login email address ID to sync the two accounts again. Seems a bit cumbersome to me.
It appears that Avast has not thought this entire "all-in-one" login out very thoroughly. The entire approach creates problems and to have a "Login Button" in an Avast forum that simply becomes totally non-functional with no explanation to the user in these type of matters certainly doesn't help either. Really, didn't Avast think this out at all?
I don't know, this all makes me a little worried about the Avast app itself if Avast can't even appropriately figure out their login interface procedure.
Maybe I'm wrong here somewhere, if so please explain, I'll be happy to hear there's an answer that I'm overlooking. I have to admit,
for me the whole "single sign-on" approach is a bit confusing as to how in the way this login approach is used will actually work very well under all circumstances that may arise.
And of course now we're having growing problems with various browser compatibility issues with this new "single sign-on" approach that Avast has decided to use.
Please provide feedback.

Btw, sorry, I know it's long
bob3160, I apologize for that, but then if you think about it sometimes a full explanation in order to gain a thorough understanding of an issue requires people to have to read a little more than they might want.
