The first unfold used to be free, and after that you needed to purchase the module to unlock further unfolds.Could it be that MQA playback does not work (any longer) with UAPP after the last firmware update?
The app indicates that an in-app purchase is necessary.
The song plays correctly on my FiiO M11 Pro without the in-app purchase message appearing.
That's a good question, but since I purchased the module a long time ago, I can't test it without making another google account and downloading the trial. But as of right now as @firesign says it isn't working to unfold past 1x whether you pay for the module or not. I just tested it again with the newest version and it is still gimped... Neutron and Mango though, will unfold to 382 on the MQAs I have to test with.I it even possible to have MQA playback without the in-app purchase?
