I downloaded Ancestry.com's new ap "We're Related" on October 25th. The first day I couldn't get it to stop loading the "Who are you?" page. I tried several times in the following week and always time out getting the "Error communicating with server, please try later. Error getting trees. We seem to be having trouble pulling up the roots." Cute but annoying.
I'm not sure if it's because my tree is so large or if there is some other issue on their end. I travel a great deal and thought it would be neat to find others who might be related to me. Definitely don't use this if you don't want your gps coordinates known!
