When on a call iMessages stop working
I have an iPhone 11promax. My iMessages turn off whenever I’m on a phone call and it will send as text instead. Here is an example: I’m talking on the phone and I try to send a iMessage but I can see the green arrow and it will only send a text message. The others person's reply comes back as an iMessage, after this the next three messages I send go out as an iMessage, other persons reply comes back as an iMessage, and my next two replies go as an iMessage and then after a few minutes the next message I try to send goes out as a text message. This only happens when I’m on a phone call. I’ve restarted my phone multiple times and tried trouble shooting, but nothing works. I don’t know what to do.. it started happening only since the last update.
