Seriously devs of this game really just thought of a method to causing a lot of frustration just by not fixing this buggy glitch. Every-time you tap on those bonus videos to get x2, x4 coins they fail to show up in the quota, same goes for the videos that reward the 1000 coins... i should have a LOT considering i click all if them , i consume my data AND no reward still. Why do you even have that feature there just to waste time and data and patience and all the rest of nicely said words in this type of situation... seriously, fix it otherwise just grinding the levels to get your ship upgraded is just too frikkin repetitive, easy to get high score
