Hi,
I have my project all in JS and I use Firebase. I added the Authentication to my app and it works fine when I use it on my PC and when testing on C3.
But when I try to log-in with Google on my mobile device it gives a 403 disallowed_useragent and I don't understand what is the issue. I followed the guides on Google documentation for the Web integration I have 2 apps setup on my project in Firebase one Web and one Android. Maybe I'm missing something I'm really struggling with this.
Thank you.
