Tom the issue is that the Hub will just be not available, or there are error messages displayed trying to access some functions like policies. So it was last time updateing the hub to 8.60.
I was in the middle of troubleshooting, hub was working first but than I wanted to access the policies and *bam*, something like: The hub is under maintenance, pleas try again later.
Since a few days we get mails now when maintanence is happenning but since the beginning using the hub, as of may 2021, the main updates for the hub where done during working hours, at least here in germany. And so far as I've seen those mails lately it is mostly CC related...
I don't know the basic avast policy for this, or if there is anything like this at all... All I can say that for Cloud Care this was handled much better and always in advance of such updates. Why can't this be adoptet do the hub as well?
