Content creation

I've been trying to set up an interactive learning activity using H5P on our Harbor course website. It takes a long time for either viewing or editing pages to load. In addition, the multiple messages appear in red: Unknown exception related to local files (Failed to retrieve file from file system [ID: etc])

Is there a workable solution so that I can develop a learning activity that works? I use a MacBook Pro 10.13.6 with Safari 13.0.5. All other activities and tools on Harbor work fine.

Thank you.

I would like all activities to accept videos and gifs over 60 MB, because it is complicated to receive only 16Mb, the images are ugly.

Hi,

I am working on a course presentation to include a variety of activities. 

I tried to copy and paste a previously created drag and drop content onto one of the slides and it replaced the whole course presentation instead. 

Is there any way that I can retrieve the presentation? What can I do to copy and paste other H5P content onto Course Presentation?
