I just installed Beta 2 of both AMS and AAT. I created an avast! Account. When I try to log into it on my phone and get to the "your phone number" part, it says to enter it in the format +1 (650) 378-1390. I cannot enter my phone number in that format as I do not have access to + ( ) on my phone.
EDIT...
OK I figured it out. I had to long-press 0 which added the +, but the example format should be changed to +16503781390.
