I have a 2017 iPad. It is running the latest 11.3.1 iOS. I use my iPhone SE’s hotspot (iOS 11.2.6) as my main internet source. After I accidentally updated to 11.3.1 update the iphone generally fails to appear in the wifi list. After a network reset it appears and Bluetooth connection is mostly possible. My iPad mini running iOS 10.3.3 sees the iPhone’s hotspot. Any help resolving this would be highly appreciated.
