iOS15.2.1 -captive.apple.com screen is blank
I updated iOS on my iPad mini 4(Wi-Fi) to iOS15.2.1. Since then, when I connect to a Wi-Fi network, the captive.apple.com screen is totally blank. I cannot type the log-in information.
My other devices (iMac, MacBook air, and iPhone SE-1st generation) can connect to the same network (Linksys router+cable modem) without any issues. My iPad mini can connect to the mobile date using tethering from iPhone because it does not need the captive.apple.com screen to log in.
Does anyone have the same issue? Is there any solution for this issue?
I would appreciate any inputs.
