I did purchase 1Password5 from iTunes on OS X, then upgrade to 1Password6. It was ok so far.
Now I have upgraded to 7 from AppStore.
To restore my license I've been asked to install it from the website.
So I have installed 1Password7 from the website, and 1Password6 has been uninstalled.
I have created one 1Password account on the website but my wallet does not appear.
Now 1Password7 is in read-only mode, and to restore the license, it asks for a file, which I don't have!
1Password Version: 7.2.1
Extension Version: Not Provided
OS Version: OS X 10.14.1
Sync Type: iCloud
