There's a workaround you can use on the iPhone. First, save away any custom files you've imported via iTunes:
- Make sure your device is connected to your computer and open iTunes.
- Select your device in iTunes’ sidebar and click the Apps header in the main view.
- Scroll down to the File Sharing section and select Bliss in the Apps list.
- Select any custom files you've added and/or settings files (anything ending with .bdf) and drag them to your computer or use the "Save to..." button to copy them to your computer.
Then delete the Bliss app from your device by unchecking its checkbox in the Sync Apps list in iTunes. Click the Apply button to sync your changes. Then re-install it by checking its checkbox in the Sync Apps list in iTunes and click Apply again.
Once Bliss is installed again you can use iTunes to copy back your custom files. Repeat steps 1-3 above, and then either drag your custom files back into the Bliss Documents list or click the Add... button to browse for them.
We also plan to allow changing player names in the next version of Bliss for iOS.
