I know I can't single handedly balance out the EXTREME bias forums like these have to the extremely tiny minority of people having problems, but, here is that little bit I can offer.
- My taptic engine is perfectly fine
- I had no problems booting up my watch
- Apple Pay worked just fine today as I learned shortly after both wife and daughter begged for useless junk from the Disney Store
- Sounds are as loud as one would expect from the tiny speaker
- Notifications are working as expected in all regards (haptics, noise, receiving them under the correct conditions)
- Basically everything is working. I can't keep track of all the weird problems. Point is just that I got a perfectly normal watch with no problems, like probably 99% of everyone who ordered. Enjoy your watches, people who are still waiting and getting nervous from reading the problem threads.
