If having issues like that on the phone app then it is easy to resolve. With the iphone click on safari and go to you ebay account and select classic and you can access ebay the same as you would on the PC.

If it is so easy to resolve then maybe you would let eBay know how to rectify the problem.

A lot of smart phones use the Android operating system and the eBay App for Androids is so flawed that it would be easier to rewrite the App than debug it.

Changing from mobile to classic view is easier said than done and due to the fact that eBay encourage members to download the app then surely it is reasonable to expect it to work.

The app is not designed to be used in classic mode but maybe a warning message pop-up frequently telling users to change to classic view because the app isn't working properly would be useful.
