I absolutely love H5P inside moodle. It's our favourite tool. Especially the new interactive book offers almost everything we need (some additional features would be nice - but nothing to complain at this early stage of development).
Also the mobile app is the perfect extension for serving our different colleagues all over the world.
Unfortunately interactive book doesn't work inside the moodle mobile/desktop app at least on IOS (and WIN 10). There is only a white screen without content.
All other H5P content types we use are shown (of course sometimes with restrictions).
We still use the plugin type on both servers, not the core implementation.
Server versions: Moodle 3.8.4 and 3.9.1+ (20200903)
Moodle App: 3.9.2 (also Desktop version 3.9.2 on WIN 10)
IOS: 12.4.8 on Iphone 5, Ipad Air
Is this a known bug originating from the mobile app or a limitation of the interactive book due to it's early development stage ?
Any hints for solving this are highly appreciated
Keep up with your excellent work and stay healthy,
