Find the Hotspot

I noticed a while ago that some content types had disappeared from pages on my experimental dev Wordpress. Everything I have is updated to latest versions (H5P, WP, plugins, latest Chrome version, etc), so I couldn't quite figure out what was going on. The activities showed up fine while being created in the editor plugin, so it was a mystery that things like Memory Game and Multi-Hotspots didn't display when embedded in pages.

We are in the process of upgrading our H5P from vs 1.19.1 to 1.21.0

We are using Totara Learn version 12.23

In our current version everything works well with our H5P activities.  I am now testing  them in vs 1.21.0 and am encountering issues regardless of browser; an am using a laptop.

My interactive videos have the message: "Cannot read file. Either the file does not exist or there is a permission problem"(image attached) above them, but they do work.

Hi! I love creating with H5P. I think it's the best plugin ever. Could an audio file be added to the options in Find the Hotspot,please? That would be great help to teach very young learners. Thanks.
