Changes to Presentation not saved in WordPress
I keep almost randomly losing changes to my presentation when editing a presentation in WordPress. This often happens when I cloned a slide but also when simply making changes to content types used on the presentation. Sometimes it does happen, sometimes saving by using the Update Button works. I have looked through the forum, there are reports of issues like that in 2017 but I can't find anything recent
I am using WordPress 5.6 together with AMPPS 3.9, the H5P PlugIn version is 1.15.0.
No other documentation that I can add because it is not like I get messages that the Update didn't work or similar. Saved work simply disappears!
Any advice would be appreciated,
