IOS and Android callbacks doesn't work

api

#1

Hello!

Our twitter application stoped working for iOS and Android platforms.
It showes:
Callback URL not approved for this client application. Approved callback URLs can be adjusted in your application settings

But when we tried to add SDK callbacks like com.vk.vkclient://twitter-oauth/callback, we couldnt add it to approved callbacks list.
What fixes should we for fixing this error?

Thanks
