Poor/no signal after iOS 14 update

Ever since I updated my iPhone X max to iOS 14 I have had poor signal if not none at all. Most times my calls don’t go through or I have people tell me that they have been trying to call me. The Internet rarely works unless I’m connected to a WiFi. Plus my phone is constantly getting hot! I have been asking people if they are experiencing similar issues and every other person says yes. I called apple customer support. They ran diagnostics and told me everything is fine. But this is untrue. I have been an apple customer since day 1 but I feel as if they either are choosing to not acknowledge the issue many of us are facing or simply do not care. I promise I am not trying to be rude. I genuinely feel this way. Every time I speak to a rep they immediately want me to send my phone in for repairs. Keep in mind, my phone is about 1 year old and I had no issues what so ever prior to the update. At this point I am convinced that the IOS 14 update ruined my phone and apple pretty much told me too bad. I guess it’s finally time to switch. Anyway, anyone else having similar issues or any ideas on how to fix this?
Having same problems
