New pro WiFi deadlock, straight swap with existing product.
Auto lock takes 3 cycles to fully extended the bolt, unlocking will not fully retract the bolt (takes 3 cycles and leaves about 15 mm hanging out,this can be pushed in by hand)
Sounds to me like your bolt is hitting the side of the strike plate just slightly. May need adjusting if you can. Happened to me also after I changed locks. Not sure why. Had to find a plate at hardware store that was a touch skimmer and now works perfectly. You can test theory by taking off jamb side strike plate entirely and seeing if works smoothly.
