Description
I’m creating swift app with zoom meeting sdk and trying to authenticate via zoom. I setup General app 331 with OAuth Information
Development
OAuth Redirect URL

I made sure callback url is correctly setup. I don’t see callback in xcode or django logs. Only thing I see in xcode is

I tested via curl and browser

I do see django logs

So django callback url is set correctly and I see logs but some reason zoom isn’t redirecting and giving 4700 error.

Error?
Oops! We were unable to complete your request. Please try again. (4700)

Debugging futher I see there are below options in Build your app → Features - > Surface . I updated as below but same issue. Maybe it takes some time to update?
