Been using the paid version for almost 2 years and still have the same problem since the beginning: I cannot remove deleted messages/conversations on remote devices/Chrome extension. I have tried disable/enable SMS service. I have deleted/installed all instances of the app and deleted all files from Google Drive but messages keep coming back (but not on the Google Messages app on the phone). Yesterday was the strangest as I sent a txt via my tablet and it now shows a conversation that was deleted over a year ago. I again uninstalled all the join apps (2 tablets, chrome ext) and deleted all files from Drive. Reinstalled everything, ran diagnostics….and now 2 old messages/conversations are back. Any ideas what to try next?
