I was having problem that whenever I hit some good raid or hit wheel bonus on Viking guest game then game and app just closed , when I came back to that everything was gone no raid no bonus wheel. When I complained about this to coin master that just gave me advice than all apps need to be updated and use strong wifi
They should look into this because more people having this problem . Giving people rewards spins this is nothing for them . Many people spending money as well as I did and game is not that good I mean there is more problems that need to be fixed .
