Problem with in game offers – Motor World: Car Factory Review

I really enjoy playing the game and there is plenty to do within the game. The only problem I am having is when I watch an ad in order to receive an in game product I do not always receive The product. An example of this is when watching an ad to skip research I will watch the ad and then not receive the time skip for the research. If this problem could be addressed I would enjoy the game much more. Thank you.
