I've noticed that 1P behaves weird when switching between multiple Mac accounts on the same computer. If I updated 1P on one account, then switch to the other, it checks for new updates every 5 minutes or so and pops up with "thank you for running the latest version". It's interrupting my workflow as it brings that window into focus.
It seems as though one account is still stuck with the old binary in memory and the other is using the new code. I noticed Brave browser having the same issue (updates on one account makes every new tab crash instantly and a restart of the app is necessary).
I noticed too that when I checked the version the first time it still said 7.8.1 BETA2 and when I rebooted my machine it said 7.8.1.
I know this is all a bit vague so let me know what I can do to make this report more clear.
