2. If i disable updates for beta, will I stop geting false update notifications and only get genuine ones going forward or do i have to uninstall and reinstall? Too time consuming to manually check updates for the beta vers.

The problem isn't RTM vs Beta. The problem is that the Object Desktop app doesn't recognize your installed versions correctly. You can only compare versions correctltly here:

by comparing installed version to what's available in the list (after navigating to the above link and clicking View Individual Downloads). Disabling beta updatevnotifications will only disable that, not all false notifications).
You didn't answer the question I asked you in reply #5.
