I'm having the same issue on my iPad. Everytime I start the app, it has an error dialog:"Unable to download favorites". I followed the directions from the link above about deleteing the app from the iPad and resyncing it from iTunes. That didn't fix it. To give more info, I'm do have guide data when I watch from the computer. Also, this use to work for me and then my power supply went out. With the new slingbox unit, the guide data has never worked from the iPad. One other thing I've noticed with my account is I don't have a slingboxId.
I have the same problem with the iphone, adding favorites is not possible, no channel list or hearts on the edit favorites screen. don't slingbox monitor these post and add and fix these issues? after buying an app I expect it to work. poor effort slingbox! thanks
anybody got a fix for this. I have already uninstalled and synced the app twice
