1) Followed the steps until I got stuck on my mobile with "Now enter the password when you first... you vault" 4 attempts remaining.
(or something like that)
2) This is confusing... I don't know if I should enter the Master Password for Avast Passwords, the password when I open my Avast Interface on my PC, the password when I login to Avast.com, or some other password from long time ago "when you first..."

3) Even stranger, when I look at my Avast interface on my PC now, it seems to indicate that all has already been successfully synced to my mobile; despite what I mentioned in #1 above (and even gives me the option to "Remove" my phone from the synced devices.)
4) Also, when I check my phone, seems all my passwords have now been backed up properly... so it's done and successful, right?
Am I missing something? What to do next?
