I try to send a message into a group chat, and it sends to all the recipients individually
I updated to iOS16 a few days ago, and now whenever I try and message a group chat, it is not sent as an iMessage (green bubble) and instead of people seeing it in the group chat, it sends everything to each member individually. It doesn't say that I sent it to them on my phone, but on their screen I send them what I sent to the GC. Messaging them normally works, and it uses iMessage when I do that (blue bubble) but for some reason when I message the group chat it doesn't. This only started happening a few days after updating to iOS16. I checked my Messages settings and even turned SMS/MMS messaging off, yet it still sends it as that. I tried updating to iOS16.0.2, and that still didn't work. Any help would really be appreciated, thanks.
