My Question or Issue :
So my problem lies within actually clicking on the login button and connecting that button to my desired dashboard. When my Android studio runs, everything works perfectly when I click on the button, but when it transfers to the actual website it messes up. It just gives me a blank screen and nothing else. I tried everything and made sure that my redirect URI was connected to the dashboard and it was. I tried the log.d function in Android Studio and it worked, and I tried making sure that the redirect URI was working. Every time though, I would just get the same blank screen when I click on my login button. Some of the things that I did not add were adding the fingerprint and the package and I did not try the openToBrowser method instead. Any recommendations would be greatly appreciated because I was working on this yesterday for like 3 hours and nothing was working.
