Immediately after updating to the latest 1Password 7 beta, I started seeing this debugging dialog info…
I checked out
com.agilebits.onepassword7-updater. The key didn't exist in the former, but it did in the latter, however deleting it didn't have any effect after restarting the helper app.
I am running macOS developer betas (Beta 3) on my laptop, but it didn't seem particularly related given the messaging.
