Erroneous function of the "Project Thumbnail Grid" on mobile when selecting the "Layout Mansory", where videos also appear in the Project Thumbnail. You can't get back to the point where you were before. You always get to the beginning of the Project Thumbnail Grid.
If you set the layout of the thumbnail grid to "top aligned" everything works fine.
I was able to work around the problem for the time being and separated the desktop version from the mobile version: desktop version in "Mansory" layout and the mobile version on "top aligned". lol
