I'm also getting this issue. For the most part, songs play correctly and as expected, but there are select songs that produce Code 6, specifically Calabria (Firebeatz Remix), id 927908043 SDKPlayback] Failed to prepareToPlay error: Error Domain=MPMusicPlayerControllerErrorDomain Code=6 "Failed to prepare to play" UserInfo={NSDebugDescription=Failed to prepare to play} Any idea why certain songs fail to play?

Hi there!We are also experiencing the same issue where we cannot apply a promotional offer (i.e. 1 free month) on an active subscription in the sandbox environment. We are, however, able to successfully subscribe with no promo offers and also subscribe to a new subscription with a promo offer for one free month.Is there any update on this? It's extremely challenging to test this in the sandbox environment without knowing if this will be the case in production.Thanks!Eann
