First of all thank you guys for your replies! I appreciate.
This first game was first of all a test for me, in order to learn how unreal engine and the publishing system work.
To be honest I don’t know how to create an option to login to google. As Smcqueen noticed, I only know that UE automatically login as soon as the app opens, but if there is another way I’ll be happy to add it. Anyway, the record is store also locally. Or at least it should save locally, in my phone works but it is just my phone.
Thanks again for your replies!
