Any functioning cache? For me emails disappear and reappear after refreshing.
Does it receive GitHub verification emails sent to a private alias? I wasn't able to receive one as it used to happen with Nmail (but was able to receive sent mails from the same alias):

Wow, that must be an important fix then; I see the emails from GH now, thanks!
Another thing I noticed is that alias probably never worked for me. I've created a private one here https://uid.ovh/dashboard and added it here https://app.nostrmail.org/settings/identities but can't receive a confirmation email from GH, for example.
