iPhone users: Renew Premium via website, not the phone app

PSA for iPhone users: If you purchase/renew your "Premium" membership through your iPhone app, it costs 30% MORE. I went to renew mine on the app and it said $18.99 per month, so I thought there was a price increase. But I went to the website and it's $139.99 per year.

So always renew from the website!
