I forgot my master password and have a one year Apple subscription. 1password support recommended I canceled my apple subscription, and then you were able to delete my account.
I have now created a new account with the master password written down safely.
I uninstalled 1password completely and restarted. I now have a new trial. However, I don't see any option to "Apply Purchase to Account" under Preferences. The yearly subscription expires October 6, 2019.
Do I need to sign up for a Trial using the SAME email address that my Apple ID uses? Account Preferences then give me the option to Apply Purchase to Account? I've added and confirmed this second non-apple id email as a secondary account at https://appleid.apple.com/account/manage
My subscription says I have 180 days, it's only been about 45.
EDIT: I created a second account using the email address I used in my AppleID and still no option to Apply Apple store purchase.
