I am working on a React Native webview app for a Ruby on Rails website. I added Push Notifications using Firebase Cloud Messaging. My colleague integrated the Google Calendar API into the RoR website, and it works fine when on the website. But, when trying to sign in to google in the webview app, I'm getting this error.
I tried putting the objective c code of this solution into my AppDelegate.m, and it prompted me to enter my gmail, but then gave this different error.
I then tried putting the objective c code of this solution into my AppDelegate.m, and it allowed me to sign into google properly. However, it broke my Firebase Push Notifications, so that now it will not ask the user for push notification permission.
Has anyone had a similar issue and know of a solution or ideas? Is there a good solution that allows a webview app to sign into google and use firebase push notifications?
