I'm trying to deploy my apps to Firebase but having some issues with pointing custom sub-domains.
Say my root domain is example.com and I have deployed my first app successfully using a sub-domain app-01.example.com.
Now I want to deploy another app to app-02.example.com. However when I try to do this, I'm getting the error "This domain is already in use".
I wasn't able to find much on this issue, it appears that it has something to do with the SSL certificates and if that's the case we'll need a different root domain for each app we're deploying. Are there any workarounds or am I missing something?
