I am upon disappointed with Apple with this. Was told it must be my internet provider but reading what everyone else has written I too have been experiencing the same things on all our updated Apple devices and that’s about 5 too many! Connectivity issues. Wifi disconnecting constantly. Dropping calls on phone saying no cellular service wifi not connected dropping service. Apple told me reset my device. It’s not just one device. It’s my computer my husbands laptop iPhones and I pad. Only Mac working right is the one NOT updated! Maybe Apple should scrap 14 and improve iOS 13. Nothing but headaches and I can’t even work effectively from home now because of it. I want all my money back APPLE from all my devices so I can buy ones that are stable. NOT APPLE PRODUCTS I guess. On going Issue for months and no solution.
