Hi @ahmed.nour,

Could you please make sure that the intended callback URL was added to your Application’s **Allowed Callback URLs** list?

Please let me know how this goes for you.

Thanks,  
Rueben

This is what we have currently in allowed callback urls Also this issue doesn’t happen all the time  
`com.ourapp.app://login.domain.com/ios/com.ourapp.app/callback`
