Losing Customized Audio Tracks to my Scores after Cancelling MuseScore PRO Subscription?

I currently have a MuseScore PRO subscription. I have scores uploaded to my profile for a few years which have customized audios, since I added extra sounds in the musescore program and uploaded them directly from the program.

I plan to cancel my MuseScore PRO subscription. One of the benefits it says I will lose is 'Add a custom audio track to your scores'. Does this mean that the scores that I already have uploaded will lose it's customized audio, or only that every new score that I upload after cancelling will not be able to have a custom audio?

Thank you.
