I try to buy it from Canada, but it says only available from US store...?
Thank you for your interest in OnSong! We had a critical bug in the last update that occurred during the upgrade process. This bug only affects a very small portion of our current users, but we felt it was better to pull it from the store before it would negatively affect more of our current users. The last thing we want is for a musician not be able to use OnSong for a live event. We are working on a fix and hope to have it back on the store as soon as possible. Depends on how long it takes Apple to review and approve the build that contains the fix. Please go to the following link to register to receive updates.
We will send out an update as soon as OnSong is available on the App Store again.
Please let us know if you have any further questions or concerns.
