I admit upfront, it's my fault and I don't know how to fix it! When I first subscribed to PoolMath, I had an Android phone with Google Play. Now, when it's renewal time, I have an iPhone with App Store. The subscription auto-renewed under my Google Play which is not linked to my iphone - iphone's aren't compatible with Google Play. How can I get my PoolMath subscription to work on my iphone now? or do I have to re-subscribe and pay the $8 again?
