i have tried a few of them now and some just take too long and then at the last part of the surveys just get stuck on a loading screen for example the last question of the survey will keep loading, always the last one. and other things like the site always showing no available surveys all the time. this is so irritating and i fail to understand why gamehag has never done anything towards this
