All messages are gone!!! App would not update, I had to uninstall. Than upon reinstalling it asked me for a phrase, I never set up a phrase, next thing I know it sent me a code, reinstalled the app with one group. All the other messages are gone. DO NOT RELY ON THE APP. DO NOT SEND ANYTHING IMPORTANT OVER THE APP. I had many friends switch over to this app, as it was super to be safe. What a mistake!!!
