Let recording continue when app is not directly open on iOS

Context on this one is that when you are recording using the iOS app and you take the app out of you to for instance open an email or look through another document. The recording often seems to fail and totally stop working. It would be great if the recording could continue without any sort of issue while another app is open and in view. Think about how if you were at a meeting and you were talking through a PDF document or looking at emails you would want the recording to continue while you were talking through or looking at some document on your phone. The recording should continue. Look at the Shazam feature where the find song feature continues after you leave the app.
