I found something interesting regarding the 10,000 event coins and the flash deals.

So just yesterday when I saw the pop up for the event coins I went ahead and watched 5 ads. About an hour later it came up again, which I thought was weird because usually it only pops up once. Then I begin to notice every time I open and close the app it keeps reappearing even after watching the 5 ads. The same thing can be said about the flash deals, new items appear when you refresh the app. Idk if this is normal or if it’s a glitch. If it’s a glitch it’s a cool one because I made over 100,000 event coins just by refreshing the app after watching the ads several times. If this is happening to you to now’s a good chance to get as many even coins as you need before the season ends.
