Steinberg? Really, no response?? This was such a courteous and thoughtful request. You could at least acknowledge the OP.
I personally am very confused by your behavior regarding this app. First you sell it, then you give it away free, then you say you are going to upgrade it and restore it to the status of a purchasable app. Months have passed since this app performed as you designed it. OS7 is not to blame, IMO. I think OS7 made you realize you created something that you have no interest in. Were there not enough sales perhaps?
Here's an idea: Give a purchase credit to the people like myself who bought the app. This way everyone wins and you can stop pretending to have any interest in the app. This would be a fair conclusion to LM the App, may it R.I.P..
