"Good news! H5P for Moodle Mobile has been released. However the offline mode is not yet avaible but it is coming soon.
-BV52"
On my local Moodle test site i have the latest H5P version 1.17.2 dated 2019031301 and I can see in its folder that mobile is enabled.
To test it I use the moodle mobile test site at https://mobileapp.moodledemo.net/
Indeed the H5P activities I created do not display the icon meaning that these activities are only available by going to the site itself.So I should be able to display my H5P activity in the mobile app.
However, when I click on the link to the H5P activity I get this error message:
This site is not configured properly for displaying mobile H5P content. Please contact a site administrator.
What am I missing?
