We deployed a fix for this last night.

We are continuing to work on a fix for this issue.

For the videos below, you are able to download the video but the app will prompt you that the video has been deleted and needs to be re-downloaded because the video has changed. This doesn't affect videos on the desktop app.
This started last week and we are testing a fix now.
