Under many different accounts my experience is always the same. At first you win everything. Makes you feel like Bobby Fisher. Then you lose some but get better. Then they tell you that "coaching" will help. For a price of course. And here is the most glaring thing of all. You have long winning streaks AND long losing streaks. You beat much more advanced players then lose to much more inferior players. My best guess is you are playing against a computer much more than you think. And of course cheating is a HUGE problem.
