Accidentally subscribed to Youtube Red / Premium through the App Store. Got an e-mail a few months ago when Youtube shifted to Premium congratulating me that I was grandfathered into the old rate and features forever. I noticed their new rate of $11.99 seemed similar to what I was already paying. This is when I discovered Google had included a $3 surcharge to cover App store fees in the App store price (don't blame them). I looked into transferring and there is no way to transfer an App store subscription to Google without cancelling and starting fresh (thus losing grandfathering). Decided to stick with the App store to maintain grandfathering, but it's a bit ridiculous that Google wasn't allowed to nudge me to a browser to save $36 a year.
