S9+ docking problem (already replaced treads)
Starting a few months ago, my s9+ seemingly lost the ability to climb all the way up onto the dock. It was doing this successfully for years prior to that, in this same spot.
It also was more frequently getting stuck in other places around the house, so when I read on here that the fix is to replace the tire treads, I did that. It has nice thick treads again.
Unfortunately, this has not solved the docking problem; the attached video was taken immediately after replacing the treads.
I tried to get it to dock 5 different times, and all 5 of them failed the same way: the robot made it partway up the dock and then just started rocking back and forth in place until I manually pushed it the rest of the way.
Any other suggestions on steps I can take to try and resolve the docking problem?
