Sending iMessages from an old iPad
Hi there, so I have an iPhone SE (second generation) and an iPad (fourth generation), my iPhone is on iOS 15 and my iPad is on iOS 10, so lately I've been having a problem with iMessage so when I send and receive messages on my phone I can see them on my iPad but if I try to message someone from my iPad I can only see the messages on my iPad but they don't show up at all on my phone. Please tell me if there's a setting I have to change or if my iPad is too old and no compatible with iMessage anymore.
iPad, iOS 10
