I just wanted to say to those people that are streaming with the iRig Stream that it cuts out after 30-40 minutes on iOS. I may have solved the issue for myself and wanna share it with you guys in hopes that it will help you guys as well.
In a nutshell, DO NOT use the lightning cable.
I purchased the Apple Lightning to USB3 Camera Adapter. This has two ports that connect to one lightning cable. One is USB and one is lightning female. This means you can charge your phone while using your iRig Stream. So now use the USB cord.
This has worked PERFECTLY for my stream 5+ hours on it and no cutouts. No background app or anything. I'm not sure if that will fix it on IG or FB but on TT it worked perfectly.
Hope this helps
