Crash problem – Six Pack in 30 Days - 6 Pack Review

It gets stuck after the first day when I try to close the ad. A white screen pops up and nothing happens until I close the app. By reopening, I have to watch another app and the same thing happens in the end. P. S: They fixed it after my comment, and I appreciate their fast response.
