IMHO LR Mobile is a cruel joke. I tried it, didn't like it (for similar reasons), Uninstalled it and stopped LR from trying to sync with it.
Not only that but it only works with one catalog on one computer. You can't use it with 2 different installs of LR on 2 different computers. So I could either sync with my home desktop or my work notebook but not both. This in itself makes it a JOKE.
