I purchased a Galaxy S24 Ultra and previously had a Note 20 Ultra. While waiting for the S24 to come in, I was using a Pixel 4, and RCS texting between iPhone users worked perfectly fine.
Upon switching to my Galaxy 24 Ultra (I can't remember if it worked before I installed 2 updates on the phone when I received it), the RCS refuses to send messages (without having to tap the message long and select send as SMS) to anyone who isn't using an Android.
The strange thing is, If someone on an iPhone sends me a message, it will send it as if it were an RCS message, but the moment I go to send it will say "Waiting for user to come online"
It will constantly change from RCS chat to SMS chat.
I'm not sure if this is because I updated the phone, or maybe it has something to do with my Pixel using RCS?
Anyway, I've tried resetting RCS, reinstalling messages, opted out of beta, reset my phone, nothing works. I've contacted AT&T but they didn't really help much, and at this point I'm not sure if it's my phone, or something else.
If anyone has any suggestions, or have experienced this issue, Id appreciate any help.
