DeletedUser177 My RCS also broke a few days ago. Whenever I go to send a message, it tries to send, says "Message delivers when contact name is online" then it eventually sends as SMS/MMS. I am able to receive RCS message just fine, but cannot send them.
I've tried these steps, and also the standard turning RCS off, clearing cache/data, force stopping, etc but to no avail,
Has anyone else had an issue similar to mine?
