The iOS version does not appear to support backup and restore.

Yes, I have added other URLs.

The URL works in Safari on iOS. When I paste it into XiiaLive I get the error message "Unable to add URL link. e:-12"

Using the iOS version BTW.

I live in Takarazuka . The URL works in a web browser but not in XiiaLive. It also works correctly in TuneIn Pro.
