Hi there!
First of all, sorry for the inconvenience.
Your feedback helped us find a bug on our end: your domain’s status has turned to valid while it should be, in fact, still be pending. This can happen in rare cases where the domain is correctly registered but the certificate is not emitted yet.
This bug is now fixed and domains should now have a more indicative status (domain is valid => both the domain and the certificate are working).
Your domain status now matches reality. The validation can take up to 4 hours after the last modification -it should be live by end of day. I will circle back with you to make sure this is the case.
