Actually I closed my ticket, since I realized the issue was related to my Android rather than to Avast.
The problem now is I cannot log in to the Support site using my my.avast.com email id/password.
I guess that's because the Support site automatically created a new account with same email id.
I changed my email address in the duplicate profile on the Support site, to no avail. Could not find a way to delete that account, either.
