I have tried all these tips, and all day I have been unable to purchase. It just says "contacting." I have plenty of free storage, and my phone works in all other aspects. No internet issues on any other app. Help? You guys are missing out on my money.
And now it seems to have lost all my stored prizes -- I had around 100 of all of the boosters and they are all gone, even though I'm logged in. And my daily progress of over a year is gone. This is ridiculous.
