Text messages disappear and reappear on imessage Iphone 12 pro
I have a iPhone 12 pro and it is only one month old. My previous phone was also iPhone 12 pro and it had the same issue. Every single day I would have a random iMessage disappear and then reappear AFTER I clear the app from the background (sometimes works) or even restart the phone. The random message that disappears looks completely blank while the other messages are very much visible. I attached a picture below to illustrate this. I did turn off and turn back on iMessage in settings. I did do Manuel Set-Up in my phone then backed up from iCloud after. I also reseted my phone to factor settings not to long after. My messages are set to deleted after 30 days, which is unrelated because the messages that disappear and reappear are RECENT(less than a day old). I have plenty of phone and iCloud storage. I have at&t.
Please someone tell me how to solve this. It is very irritating that I have this bug and others seem to not have it.
Attached is proof. One message disappeared then i cleared my background message app and it reappeared with not just the missing message, but also another one that was hidden. Notice the times I circled. Unbelievable.
iPhone 12 Pro, iOS 14
