Cannot send group text message, Galaxy S7
Ever since this new addition of Advanced Messaging, I've been unable to reply to one of my ongoing group texts. I mainly get an error stating that it's unable to send the message and gives me the option to resend, edit or delete. Sometimes I get a spinning wheel, but mostly it's the former. I've gone through and deleted the message app cache and data, and that works temporarily to quickly get out a message, but in the end, it goes right back to giving me a problem. I get the Advanced Message into window and then past that I get a notification pointing to the group chat I'm having a problem with and says "this group is advanced message capable." And that's it. After that shows up, I'm no longer able to message there anymore.
I'm not really sure what to do at this point I've been searching the internet for hours.
