I designed some simple list based interfaces for my database. when loading them in app on android or iOS, I get an error message:

"this page is not currently supported on mobile. open the page on desktop to view it"

Not sure why this wouldn't be supported. each page is just a list element with some filters. a couple use groups, and a couple have a filter element. apps are all current (6.4.0 on android & 10.7 on iOS).
