I just managed to uninstall rather than update my app. As a result I lost all my data. My last back up was 12oct so didn't lose it all.
The 'import' feature has not get been applied so have to wait a while before i can re install the data i have.
Luckily I have kept a running paper trail for a while so din't lose too much. The backup feature is a little unpreticable I think I lost a few via the junk mail folder.
Otherwise not a bad app.
