Can you tell me what service you're using where you're trying to change your password? Is it Gmail, these forums, a Nest account, or something different? Knowing what service you're using will help me narrow down a fix for you.
I just wanted to check in real fast to see if you saw my reply and to find out if you still needed any help on this. If you're still needing assistance, please just let me know and I'll be happy to continue helping.
Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, I would be happy to keep it open. If there's more we can do, just let me know.
