Apps Play Services works in dev build but not in prod build


Hey there,

We've built a game with Unity and are trying to implement Play Services. When we build a development build with Unity and test, the play services tooltip pops up and shows that we have logged in and achievements/leaderboards work correctly.

As soon as we build a production build, it stops working. No pop up, trying to manually trigger a login doesn't work. Nothing.

We've added our SHA-1 key from the play console to the play services config and cloud API oauth creds.

For a few days now we've been completely stumped and can't seem to find any guidance outside of it being an issue with the SHA-1 key which we've done everything we can think to do with.

Any other suggestions? Any easy way to debug production builds without integrating something extra?

Thanks in advance!
