Windows 10, Audacity 3.0.2
When I choose File/Export Multiple, each track is exported from the beginning of the file. This produces MP3 files with a hyoooge silence at the beginning of each file.
That is, a track that begins at 1:40.0 in the Audacity file and ends at 1:45.0 produces a MP3 that is not 5 seconds long, but a minute and 45 seconds long.
Almost every track is larger and longer than the previous one.
This is quite the annoyance in an otherwise delightful new release.
