Yeah I figured it happens because they only check if there is a WHOIS record. At first I thought they registered it automatically after I showed interest (like people claim GoDaddy does sometimes), but that's why I started investigating. Looks like domains.google is the "source of truth" since Google owns .app after all. I've previously thought that if a domain is not available, there would be a WHOIS record, but I guess that's not the case here.
