Interesting. That is actually how the app works today: you actually have to tap try Stereo HD, then make a stereo recording that is at least 10 seconds long before pressing "try Stereo HD" again presents you with the paywall.
We got a lot of feedback from users (and from Apple in their App Review -.-) that that was confusing; they wanted to see the paywall straight away. So now we're considering removing that try-it-once-without-starting-a-trial mode.
Regarding exporting to mono: no, that shouldn't happen. It should definitely export to stereo. The exporting process doesn't touch the file. Would you mind sending me that audio file to [email protected] if it's not a very private recording (of course we'll treat it privately; just for internal debugging)?
