I updated to IOS14 a few days ago and have had no problems, then yesterday updated to iOS 14.1 and my phone is completely messed up. I cannot connect to any Wi-Fi (have tried several), my WhatsApp’s won’t use my phone data (although all my other apps do) which means that I am getting no messages. my phone is lagging and slow and it won’t let me download any new apps! I have never had problems like this ever before
