you get the max storage reached message because the space we can provide (on our server) is quite limited. To overcome this problem, please connect your account with your google drive account (as you already found out)
1. Which google email specifically? The gmail account I bought the upgrade with may no longer be on the phone.
if the google account is no longer registered on the phone, you'll loose premium features. The license is bound to the gmail account you bought it for (that's why you also have premium on all other android devices which are registered with the purchase gmail account)
For right now, can I specify a different google drive not associated with an email addy on the phone? Iow I can set up a googledrive and provide u the id and password.
yes, you can. log into my.avast.com and click on the tab with your name in the top right corner. Select Google Drive to create the connection. This can also be a google drive account which is different from the account you purchased the license for.
2. Since it worked fine for a few days ... maybe 60 minutes of total recording, it must be stored initially somewhere else. Can I clear/erase the old files and make that room available again? I erased old audio and picture files on the web portal but didnt work.
hm. what didn't work exactly?
