Older scores posted to the MuseScore website have become disconnected from their synced YouTube audio.

Recently, many of my older scores posted to the website have become disconnected from their synced YouTube audio.

In other words, even though the score is synced to a YouTube video (in the "Manage Audio Sources" area), when the user presses the play button, the score plays; however there is no red measure marker tracking along with the score.

Hopefully the below screen capture will help explain the issue: The top represents an existing score (although the playback is on measure 3, there is no red measure marker tracking on the synced score. The issue is fixed by clicking on the 3-dots and then "Clear Markers" followed by "Load Score Markers" as shown in the bottom portion of the screen capture.

Although the user fix is relatively easy, I have over 5,000 scores online which presents an unreasonable challenge for me to fix this for all the affected scores. My hope is that a developer might see and recognize this issue and provide a back-end correction to the website that will correct this disconnect on mine (and likely others) scores.
