It seems that google has changed their OAuth requirements so that web views no longer work.

This issue is causing us not to be able to use the rocket.chat app on any IOS devices. We recieve the following after clicking on the google login button on the login screen.

Rocket.Chat Server version 0.46.0

If this belongs in RocketChat/Rocket.Chat.iOS I will recreate it there.

@BarnumD This issue belongs to https://github.com/RocketChat/Rocket.Chat.Cordova, can you open there?

Closing in favor of RocketChat/Rocket.Chat.Cordova#159
