Latest app update changed the v4 and Panv3 (and some others like the v3 Pro) to new horizontal timeline, also some other visual changes. OGs are still vertical. According to the release notes, no change to the old v3 interface, but wonder if they’re starting to work on a consistent interface for all cams?
My Panv3 went from horizontal timeline overlaid on the video originally, to vertical one under the video at some point, now back to horizontal, but under or beside the video instead of overlaid. At some point they’ll decide which one they want to stick with 
Panv3 also now defaults to events and you have to tap “pan control” to get to that and your waypoints.
