I used iTMSTransporter to upload an XML file containing a price change for a subscription in-app product in the future. Now whenever I delete the upcoming change from App Store Connect, click Save, and refresh the page, the price change comes back!!!! PLEASE HELP!

Hello,I am working with Replay Kit 2, to record the screen, the app output audio, and the phone input microphone.This means I can have up to 3 AVAssetWriterInput instances:- 1 for the app video (screen recording)- 1 for app audio (stereo, 2 channels, 441000 sample rate, 64000 bit rate)- 1 for microphone audio (mono, 1 channel, 441000 sample rate, 64000 bit rate)I am using a AVAssetWriter to combine these three inputs. (using add: method)This results in an mp4 with two different audio tracks, one with only the app audio, and another with the microphone audio. This means in some players like VLC only one track at a time is played.Is there any specific way to combine both inputs into one in the final MP4?
