I’m assuming you don’t want the Nest PAN network, as was my desire. I think I ended up deleting all the thread networks via Home Assistant web and then created a new one using the companion app on my Android phone. I feel like that was the only way to create a new set of credentials.
I have this link in my notes too…
The whole think is very confusing. Sorry I can’t be more clear as it’s been quite a while.
I now avoid updating anything Matter b/c my one Matter mail-slot switch always ends up offline
