Hi, I am testing using a branching scenario, created on the H5P site, enbedded (via iframe) on a test page. I am finding that it displays in Chrome but not Edge/Firefox. However the embed of the 'Art of Europe' from the showcase example does appear on all browsers.
See for example: https://learnbase.com/3470-2/
Any ideas what I may be doing wrong?
ps When I added branching scenarios directly on site to H5P install I think it may have conflict with Question sets which would not load until I reverted site to date prior to adding branching scenarios (?)
