App works ok, on pc it doesn't keep the filters, especially after viewing photos. I also have an issue MT are looking into, in that I can't vote on any photos. They've suggested the usual clear cache/cookies but as this is happening on several pc's, even one's that haven't even been logged on to MT this isn't the problem. I think I've narrowed it down to an IP address issue as it does work away from home and using mobile to tether - now back in their court.
