There's some unavoidable reasons for this bad type selling:
- I'm a Taiwanese, and Google Market does not offer selling paid apps in Taiwan yet. I'll complain Google is soooooo slow on this, but the only thing I can do is to wait.
- I'm now generating keys manually, and since I can not use full time on Meridian, massive orders will knock me out.
- The "Upgrade" button in Meridian is planned to be enabled if one of above two problem is solved. I'm asking about someone to make a PayPal-paying webpage that can automatically generate keys, but no response yet.
- Pro version by now does not have many features. At least I want to implement PlayQ picking and another music playing view.
- By the way, I plan to sell Pro version with $2.99.
