Musescore.com playback ignores dynamics, plays full blast.
I wrote a short quiet song, uploaded it, and it plays back full blast in the website and I don't know why. You can find it here: https://musescore.com/user/27819778/scores/6768825/s/CvYWz4?share=copy_…
Interestingly, if you open the mixer and change "audio sources" from "musescore audio" to "synthesizer", then playback in the website will have the correct volume. It isn't a great workaround since I don't seem to be able to make that the piece's default.
Here's the version of Musescore I'm using:
OS: Windows 10 (10.0), Arch.: x86_64, MuseScore version (64-bit): 220.127.116.118021803, revision: 3224f34
And my browser is Firefox.
