Yuku introduced the new app in 7/15, lot of criticism right from the start. Very slow, it crashes. Can't post pics to forums. Much harder to use vs the earlier app.
Well here it October 2015 and they haven't fixed any of it. Now it's a free app so they hammer your profile page with ads and pop ups and redirects while you attempt to log in. Horrible app to use. Not user friendly at all. Do waste your time trying to get anything out of yuku support, they'll just blow smoke ip your $#*!.
