Hi PapalPenguin,
Welcome to ask the Microsoft community and we'll be happy to help you.
We are in the same situation as you through testing, the user interface and functionality on the iPad, especially when using the Edge browser, may be different from the Edge browser on the PC due to the limitations and design guidelines of the iOS and iPadOS platforms. On the iPad, the Edge browser may be designed to be more touch-friendly and have a cleaner interface, whereas on the PC, it may offer more features and more complex interaction options.
If you encounter limitations in the Edge browser, try using the Safari browser to see if there are more options or better support, as Safari is optimized for both iOS and iPadOS. You may want to consider cross use.
I look forward to hearing from you and sharing more information.
