Hi, i have build a simple shop and want to use my PayPal Plus Account, so users can pay per PayPal, Credi Card and Bank Account. In Sandbox Mode everything works perfect, but when i switch to Live Mode an use the Live credentials for my app i got this: {"error":"invalid_client","error_description":"Client Authentication failed"} I have tried 3 different Apps now, but nothing worked. Do i have to make an review process or something like that to use it in Live Mode?
