I am a Pro Textra SMS user. I upgraded my Verizon Note 3 from Textra v3.18 to 3.19. After the upgrade, most of my messages that had been "locked" have disappeared or been deleted. Also, many messages have been duplicated. I attempted to Resync via Settings...did not work. I attempted to delete Textra and reinstall...did not work. Where did all my locked messages go? I NEED them!
