Thinkware is split into 2.
I’ve had this odd problem with Thinkware. It appears to be split into two. Account.Thinkware.com and Support.Thinkware.com
They don’t appear to work. For example, for Thinkware Support with 72 Characters Max and Thinkware Account with 16 Characters Max.
Thinkware Support is run by Zendesk. I kept overriding the old Passwords possibly with each Password change between Account and Support. Per se it’s not a 1Password issue but it’s frustrating.
