After some research I'm almost 100% sure its because of the Cross-Origin-Opener-Policy blocking the window pop up.
Does anyone know how to fix this ? This is getting me very frustrated. This kind of setups are always a pain to deal with C3. I'm trying to make this work for quite some time I made it work for Android export from C3 and Unity, from a localhost simple webapp, also using JS on C3 this works but if I can't run it on the C3 editor this makes it impossible to work.
I leave a print of my console after starting the game and clicking to sign in. Be aware this project has nothing else beside a sprite to click to Sign In on Google Play. The last 2 warnings and 2 errors only show after I click the button.
Any C3 developer can give me a light on this ?
