Without an example that show the issue or knowing the flow of your code it's really hard to help you for anyone.

No, don't use Msgbox or Msgbox2. Msgbox, DoEvents and other synchronous dialogs used a synchronous mechanism designed by Erel in the early days of Android as Android, by design unlike Windows, does not implement synchronous waits while letting the message loop run. Unfortunately over the years the Android message loop handling has become more complex and as a result Erel's synchronous mechanisms is now flaky - hence, Msgbox, DoEvents and all the synchronous dialogs are deprecated but available in case of need for backward compatibility.
