It's just unfair – Explore Shanghai Review

I purchased this app long time ago and have been using it for years until recently I tried to install it on my new iPhone. Why do I have to pay for the so-called VIP mode which offers exactly the same functions I've been using for years. Do I get a refund for losing the prior version of the app? That's unfair and disgusting.
