Switch between channels doesn't work (Nightly -> beta or stable)

Hi, I've been having a similar/related issue to this on my Mac —

Ages ago, I was using the 1Password 8 beta, which I had installed concurrently with 1Password 7. After a few days, I uninstalled 1Password 8 and continued using 1Password 7.

Now that the production release of 1Password 8 was available, I installed that and uninstalled 7. But somehow 1Password 8 set itself to the Nightly track and downloaded the latest Nightly version. Even after I switched the release channel setting in Preferences to the Production track, it continues updating to new Nightly versions.

I tried uninstalling the app and reinstalling the production app, but then I get an error saying "You've used a newer version of 1Password on this computer."

I was able to download the beta app (currently 80800011) and get that one to open. If I keep the release channel set to Production, will that app switch to production eventually? Or do I have to manually install the production app once 80800011 is available there?
