Using updated play-services-auth

Hello,

I am having a deployment error where the game crashes when tryin got invoke play-services-auth, given a missing class.

I have narrowed it down to likely being due to it using play-services-auth 11.8.0, and I have been trying to update it. I tried updating the aar-imports file, however while the other imports update I can’t seem to get play-services-auth to use anything but 11.8.0.

Any guidance anyone can contribute would be great!
