We have a web app involving trading virtual token. Users create account and are given a virtual wallet. They feed wallet with real money via credit card or bank transfer. Then, they buy our virtual token with their wallet credit and we collect fees at each purchase. We use banking API for money transfer and management. We also plan to put our token on blockchain(s) and trade via cryptocurrencies. 2 questions : if we develop an iOS app and distribute it on AppStore, will Apple accept such features and not reject this business ? will Apple’s commission of 30% apply on purchases or transfers ?

I use usdzaudioimport to embed a simple audio file in my usdz. But in QuickLook (iOS or macOS) the audio is never played. What I've tried : usdzaudioimport ./myfile.usdz ./myfile.usda -a /test audio.mp3 -auralMode notSpatial -playbackMode loopFromStart usdzip myfile.usdz myfile.usda ./0/* where ./0 is the asset folder of myfile.usda I tried with usdc usdzaudioimport ./myfile.usdz ./myfile.usdc -a /test audio.mp3 -auralMode notSpatial -playbackMode loopFromStart usdzip myfile.usdz myfile.usdc ./0/* I tried with usdz without converting to usd(a/c) usdzaudioimport ./myfile.usdz -a /test audio.mp3 -auralMode notSpatial -playbackMode loopFromStart I tried m4a and mp3. I tried the sample cube from Reality Composer by adding my audio.mp3 as behavior at start of scene and exporting in usdz for Quicklook. But none of this solutions worked. I'm not able to play any audio with AR Quick Look usdz file at the start of the scene.
