I am part of a group text and receive other's messages, but mine won't send
I have been having problems for awhile now with group texts on my Galaxy S6. I am part of a group text and I receive all messages from everyone in the group. For some reason, I am not able to reply to the group. I have tried changing the settings, restarting my phone, but nothing seems to work. When I type my message and hit send, the send button indents like it normally does when my messages send, but nothing happens and my message does not send. Please help or tell me if I need to take my phone to a store.
