Thanks for the comment Rob! I don’t think Firebase allows multiple service ids for a single application. On the bright side, once you build standalone, you won’t need the Expo service id.
This is also a problem for people without a web login, because once the site is live, if you switch your bundle ID back to test locally in Expo, you break things for your real users. I do not have a good fix for this: if you come up with one please post it!
