I thought the work around the 50 promo codes had been sorted or at least advice been given.

I supplied my feed details but received an email to say no go for the promo, so not supplying my feed to something I have to pay to access, whether it be 50c or $50.
So until the promo codes have been sorted or the App ever goes free, then I have requested an end to my feed.
No feeds then the App wouldn't work, wouldn't sell. I think free for all that supply the feeds is only fair.
Sorry to sound harsh but that's just me.
