This works! Uninstall from the play store then click the update button as instructed by JOSFER95.
I agree. The fix mentioned by JOSFER95 does correct the problem and now the Messaging+ app works.
I tried to uninstall and reinstall it with no improvement. I emailed web developers.
Didn't have the problem until I rebooted.
Same problem on my S8. Started after 5pm.EST. hope it's fixed soon!!
Been on the chat for about 15 min now waiting on someone.
I uninstalled and updated and it still is not working.
Canned answer. "But don't worry, he is personally going to monitor this and make sure it gets resolved". 🙄
