Galaxy Watch 4: Workout Screen Disappears After Update

I installed the latest update for the Samsung Galaxy Watch 4 yesterday. Since then, whenever I exercise, the workout screen suddenly switches to the watch face. The app continues to run in the background, but there’s no indication on the watch face that the workout is still active.

This never happened before the update, and I haven’t changed any settings.

I use the elapsed time display to track my rest periods, but now I have to keep reopening the workout app to check.

Has anyone experienced this or knows how to fix it?
