Hello folks,

Is there a way to get Bitmovin working with Axinom for Flutter/Fairplay?

Keep getting:

[BMP] [Player] [Error] Event: SourceError, Data: {"code":2301,"data":{"message":"The operation couldn’t be completed. (BitmovinPlayerCore.FairplayResponse.Failure error 1.)","code":400},"timestamp":1746296769.142633,"message":"The operation couldn’t be completed.
