Apple Watch set to count stairs

If you are having problems Correctly Counting Flights of Stairs

How to use Water Lock and eject water from your Apple Watch - Apple Support

FWIW one user said he talked to some Apple Watch engineers and they suggested:

1. locking the water (swipe up and hit the water drop),
2. washing the watch with alcohol or soap/water,
3. flush the water out per the instructions - pull on crown.

It worked! Voila! Miscounting flights of stairs problem fixed.

Apple Watch counting too many flights - Apple Community

NO. It doesn’t record flights of stairs automatically. It records changes in altitude. It will note, for example, that I climbed 249 feet in altitude during a walk and it will record the “flights of stairs” as 3... I guess each flight of stairs was 83 feet high. This is useless. What’s going on here and how do we fix it. That is the question.

It already counts flights automatically.
