Unlocking U200 skips rotation - fails to open

Calibration using app, both manual and automatic, can be done successfull, but sometimes unlocking fails afterward The unlock movement will always start, but will halts on the way and sound like it skips a gear, while trying to resume motion Anyone with some experience on this? Attached videos of different behaviours Note, the lock has been running fine for a few month and sometimes it will lock and unlock perfectly [IMG_5959] [IMG_5960]
