So the Dev and Canary Channels for Microsoft Edge are both out for Mac and I was curious when there'd be a beta for 1Password?
I attempted to install it by enabling the "Allow Extensions from Other Stores" option but it was unable to connect with 1Password every time it tried.
Update: 1Password X seems to work fine with it, though...
1Password Version: 7.3-Beta-12
Extension Version: 220.127.116.11
OS Version: OS X 10.14.5
Sync Type: Teams
