If you Google Android 11 issues you'll find Pixel owners have so many since September already. I updated to Android 11 on the 25th of December and only have data issues. I can make and receive calls and texts only. I found that by going into connections, mobile networks then select 3g and wait for "H" to be displayed then select 5G and im good until I turn my phone off. Same procedure every time I turn on my phone. Samsung had no clue and wanted me to send in my month old S20 FE 5G for repair. Very poor service and I'll definitely be considering an iPhone in future.
