I'm on the Individual Plan, billed through the App Store. My subscription should be managed in iTunes.
However, my subscription cannot be found in iTunes. I assume it is because I changed my country of Apple ID from Japan to USA.
When I started to subscribe, I purchased 1Password through Japanese iTunes Store. Currently, my Apple ID has changed to USA. My credit card, billing address, and iTunes Store are all USA's.
I am not able to access to my subscription either iTunes or 1Password website.
1Password Version: 1Password 7 Version 7.3.2 (70302003) Mac App Store
