questions about libraries updates
I have a multisite install where I have installed and network activated the H5P plugin.
Then, I have created several sites and I have been able to use H5P Activities on each of these sites, and it worked well.
I have understood that I needed to upload the H5P Libraries Activities on each site to do so, but it is not a problem. It makes sense to have different sites using different Activities, and the upload process is very straightforward.
