I tried to playback songs in flac files on iPhone, but it never starts playing. mp3 music works fine. I also tried on Android app to play the flac files and that works too so this might be a compatibility issue with flac and iOS. Could you Investigate this? I have Streamer Premium and use Helium Streamer Launcher 188.8.131.528. Thanks.
I have the same problem with FLAC on Android (Honor 9, Android (EMUI 9.1))
Thanks for reporting this. We will test this further to see if we can identify it.
