Still stuck on 7E93 - iPad M4 / APP2 USB-C - connected via USB-C to iPad Pro and iPad Pro connected to WiFi. I have no issues with the beta slider and running iOS 26 beta (non-developer). The trick is to my knowledge if the APP case is closed this disconnects the BT connection, and having the lid open enables the BT connection. Im baffled why such a complex process when an iPhone update is easy.
UPDATE: About 2 hours later the firmware is now 8A324B and the case is: 74.10.0 however I suspect the case version will stay the same.
