I tried

I have emailed you before about updating Virtuoso Piano Pro 2 with the
scrolling key feature. you did say it would happen.

I see that version 3 came out. SO. I decided to redownload VIrtuoso
Piano Pro from the app store. In doing so, I was charged again, AGAIN,
because you have apparently removed 2 pro from the app store and
replaced it with an almost identical version, save the name. DO you
not see how confusing that is? ITs the same icon, same price as 2.
How could I not be confused. You have tricked me out of $1. Very bad
form and it HAS been reported already to Apple. Im very disappointed
by your behavior. I cannot believe you would mislead people like this.
AT the very least I am owed that $1 back. Seriously, there is no
defense to this. You removed the original Pro 2, replaced it with THIS
version, and confused people looking for the original app. Bad form.
BAD form.

Look, PeterB. Ive tried. Lots of others have tried. At one point you answered my email by saying the updated Virtuoso Piano 2 that I PAID for would be updated to be just like the free version, meaning the scrolling key feature.

It never was.

And now? You release Virtuoso Piano 3 WITH the scrolling feature.

But I have to pay for no ads. I already paid for version 2 which you said would get an update for scrolling keys.

I feel hoodwinked. Swindled. Yes, its just a buck, but still. Disappointed.
