SAB App not playing FCBH audio files

I wanted to ask if anyone is still experiencing problems with the audio streaming when us the FCBH Bible Brain system. I noticed this pervious forum (Anybody having trouble pulling FCBH audio files from the cloud using DBP4 keys?) that address this topic 8 months ago.

We have both an iOS and android app. The iOS will not play any audio files and the Android can only play the OT files.

I am currently in chat with FCBH directly about the problem and it sounds like they are able to render apps with audio files I am using no problem, so I am not quite sure what is going one.

Here are the set ID’s I am trying to use:
ileset ID: TRKBSTS2DA-opus16 & TRKBSTN2DA-opus16

The Audio files in our app download ok from FCBH–either server, but SAB will not start playing the file without repeated attempts. I have reported this bug. See below for more detail
