Hello!
I have problem with App Card for my app.
When I try send tweet with App Card returns error:
rror Domain=TWTRNetworkingErrorDomain Code=-1011 “Request failed: bad request (400)” UserInfo={NSLocalizedFailureReason=, TWTRNetworkingStatusCode=400, NSErrorFailingURLKey=https://caps.twitter.com/v2/cards/create.json, NSLocalizedDescription=Request failed: bad request (400)}
I gotten permission to show this card. Image Correct and showed in preview.
