What you’re describing seems to have been mentioned recently here:
I’m seeing it on a Cam Pan v3, as well. Tapping Waypoint 1 appears to no longer do anything. Tapping Waypoints 2 & 3 makes the camera point at different spots on the ceiling, which ain’t right at all. (This camera has always been indoors and has had 3 Waypoints set for well over a year.) Recalibrating has no apparent effect.
If you haven’t already done so, then I’d suggest submitting a log and following that up with creating a ticket.
I wonder if your topic would get better visibility if you added a cam-pan-v3 tag (and possibly changed the category to Cameras), since what you’re describing seems to be specific to that camera.
