"Repeat measure" symbol not functioning.
S3 - Major
OS: Windows 10 Version 2009, Arch.: x86_64, MuseScore version (64-bit): 4.0.0-3289914935, revision: abc123456
The "repeat measure" % sign does not cause the repeated measure to playback. This is the most current version of MuseScore, and the issue is universal. I believe that is all; no file is attached as this affects all files.
To be clear, the most current version of MuseScore is 3.6.2; MuseScore 4 is still in the experimental pre-release stages. But in any case, this is a known issue.
In the future, if you encounter issues in these experimental pre-release builds of MuseScore 4, please report them on GitHub as requested in the announcement - the developers are not generally checking here in the legacy issue tracker.
