After Premiere's most recent update to Version 23.1.0 (Build 86), I noticed the "Go to next/previous marker" feature was no longer working properly in the timeline. The feature works when there are only timeline markers, but the moment I introduce one or more clips into the timeline with markers--or add markers to a clip within the timeline--the feature breaks, and how it breaks depends on a number of factors...
If I have an empty timeline and add markers, the "go to next/previous marker" feature will jump between the markers just fine. And if I add a clip with no markers to the timeline, the feature continues working. But if I add a marker to the clip itself (or add a clip to the timeline that already has a marker in it between the clip's in/out points), the "go to marker" shortcuts break, and the playhead will jump between the first marker and an unmarked specific frame (in one test, the frame it returned to each time was 00:00:01:19, while on another timeline, the time was 00:00:09:13).
This is, however, only if the clip is not at the starting frame of the timeline. If I move the clip to where its in point is the first frame of the timeline, the "go to marker" shortcuts begin working fine again, jumping between both clip and timeline markers. I can also add additional markers to that clip and all is well. But if I then copy the clip with the marker to another spot on the timeline--either touching the first clip or not--the feature breaks again: the playhead jumps to the marker in the first clip (at the start of the timeline) then ceases to move anymore.
If I click to a random point later in the timeline, the shortcuts will function properly between any timeline markers that don't have clips with markers between them, but the moment I try to go to a clip marker--or a timeline marker beyond a clip with a marker in it--the fuction breaks and the playhead gets stuck at that random frame it keeps returning to. (Upon further testing, it seems the frame it chooses happens to be a frame I at one point had a clip with a marker, and it returns there even after I've moved the clip away.)
The problem is clearly the markers within the clips, because the shortcuts work when the only markers are timeline markers. But when clips with markers are introduced to the timeline--whether it has timeline markers or not--it breaks. That said, the shortcuts work fine in the Source Monitor when a clip with markers is opened there.
Given I work almost exclusively with clip markers rather than timeline markers, this is a bit of a problem for me...
I'm working on a 2019 iMac with macOS Monterey (v12.5), if that's helpful to know.
