In Musescore 4, you can't add beam over rests.
S5 - Suggestion
In Musescore 4, you can't add beam over rests. In Musescore 1/2/3, the problem can be solved by this→https://musescore.org/en/node/11370, which is on the Musescore official website. However, the same process can't solve the problem when using Musescore 4. I selected the rest, and there is no "Beam Properties" palette. I tried selecting the two notes which I want to add beam and clicked the icon in the "Beam Properties" palette, but nothing happened.
I assume this problem occured because the newest version had some development bugs, so I really hope you can take time to fix this. It really troubled me a lot. Much appreciations.
Just use the beams palette
