Mine is greyed out also, Mine was ON by default and hand wash counts down and detects very well, just the at home reminder won’t work due to the home address issue on my card, it’s greyed out as i mentioned and do have address on my me card, if I am using my watch and go into handwash tab for split second as it flicks from handwash tab in watch settings to being in the handwash sttings, I can time it correctly where i can turn home reminders on before it greys out, but it remains grey even with toggle on for home reminders but soon as i exit it turns toggle back to off and greyed out again,
I’m curios to see if the posters on here saying there’s work, are on “PUBLIC/DEV” watchOS7?¿ I’m on the Dev beta, using series 5 watch in Aussie
I’ve also tried wifi and also cellular on my watch and this makes no difference either
