Unable to update due to 'Read Only' bug

[ConnectCreative]

Running 1.9.1.952 on Mac OS 11.3 and get the following error when I select 'Check for updates' from within Publisher:

Affinity Publisher Beta can't be updated, because it was opened from a read-only or a temporary location. Use Finder to copy Affinity Publisher Beta to the Applications folder, relaunch it from there, and try again.

But that's not the case, its installed in the Applications folder as normal?

As far I know: 
1.) v1.9.1.952 is the most recent APub beta.
2.) In Beta versions the in-app-update feature never works yet. (though I don't get yours but rather the message "You are up-to-date! (...)", regardless of an existing update.)

In case it's meant to be a question: To detect an app path: in the dock cmd-click on the app icon > it will open a finder window with the app file selected.
