Text Messages that come delayed for up to 4 days or Not At all.

Has anyone had this issue fixed? My phone started doing this too. My calling got horrible too. I got a new phone and Sim and did the smart switch. It was fine for a few days until today it started delaying text messages (nor receiving). I am thinking it has to do with an app that might be messing it up. I am going to try to remove the T-Mobile Digits App and see if that helps. I am thinking that is the culprit. Will advise in a couple days. In the mean time, I have to put my phone on airplane mode and then take it off. As soon as I do that, everything starts working again. I also feel like the resent update may have affected this because I have been fine for the past 2 years with the same phone A71 5G, same apps and only recently it started doing this.
