Yes, it's an issue in the Nest, I'm currently investigating why it refuses to unrecord.
Thanks for reporting!
Good luck, then!
Looks like it was fixed?
Yes, but now there are others, like in https://nest.pijul.com/pijul_org/pijul/b69e09cf58f63c467639
Let's keep this issue open. I'm currently testing a "nest repair tool" I've written.
There is still two conflicts @laumann is fixing.
I just applied that pull request.
