I have searched the forums and performed the recommendations of Ruby ( one of the team members who seemed very helpful on this discussion :After updating to 1 Password 7.4.4, it does not communicate with Safari 13.1) I still cannot see the extension or get it from the App Store . I use Mojave OS .
I believe this happened following a recent Safari update from 12 to 13.1.1. ( although I do not understand how to confirm the timing of prior Safari updates)
1Password Version: 7.5
