"Expressive" Voices (single note cresc/decresc) completely missing from Flatpak version
1) Install the Musescore 3.6.2 Flatpak on a supported Linux distro (elementaryOS 6.1 in my case)
2) Create or open a file that contains a long note with an audible crescendo/decrescendo
3) Notice that the crescendo/decrescendo does not sound as it should in playback, and that "Expressive" voices are missing from the Mixer.
This is a major flaw for my use case, as the DEB in the Ubuntu repos is still on 3.2, and the appimage "stops responding" every few seconds. Flatpak is objectively a major player in the Linux app distribution space, so Musescore should be running its best as a Flatpak.
