Maybe you have problems with wifi i went on vacation and hotel wifi disconnected at night and when i woke up i saw myself disconnected so this can be problem i guess
This also happened to me 2 hours ago. I was about 45-60 mins in to my flight and I had tapped my iPad screen to see how it was going and noticed I had disconnected. My wifi was fine, on my phone TV and on the same iPad flying.
This was on a
iPad Air 4th Gen
iPadOS 18.1
