Yes, I have been having chronic connectivity issues since the 14.2 update on my iPad.
I tried all the tips and tricks everyone else has, but it has not helped me. My iPad won’t stay connected for longer than a few minutes at a time. I have to constantly turn wifi off and back on. Casting to my tv has become impossible.
I agree with the previous poster who said these little solutions are just a waste of time - Apple needs to fix this iOS, please and thank you.
