Hello, suddenly we have a problem setting the thumbnail covers in the video gallery and no error is returned. It's simply no longer possible to set the thumbnail images, but the video, itself, is correctly playable by members of our community. The previous uploaded thumbnails are still there and they're all visible.
The problem did not exist before the latest update 4.7.16 (update which ran without any issues).
We attach a video showing the problem.

Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.

 

Thanks Marc, I look forward to your update
