iMessage messages not sending through and disappearing

I have an iPhone 14 Pro and have been dealing with this iMessage error for at least a year. For some reason, in certain iMessage chains I will send texts but they seem to never go through. They initially appear to send as normal, but then the blue loading/sending bar will appear at the top. The messages later disappear as if they were never sent. Sometimes messages also disappear that have been sent through. The issue will sometimes resolve if I turn my phone off and back on. My phone is fully up to date with the latest IOS as well.
