I did not leave the conversation.
I got a new iPhone 17 a few weeks ago. I have two parents on iPhones and a sister on an Andriod. When I send a text or a picture to them, it has been failing to go through. Not only that, but my phone is making me leave the conversation. When it comes back as Not Delivered, it boots me out. I have lost all of my messages with my family thread because of this forced leave. If I rebuild the group text and try again, it forces me out again. No one else on the other end is booting me out of the conversation. What is the issue here? Is there a setting to fix or is this a bigger known issue? Two screen shots are below.
