They used to show me how many coins I had purchased at all times, and they used to have a round yellow button on my profile that I'd press to buy more coins when my balance was low. First, they removed the coin balance, and I can only see how many coins I have left for a split second when I spend a coin. Then, They replaced the button to buy coins with a button that looks almost the same (exactly the same at a glance) with the Spotlight button, which costs 2 coins. So, when I noticed that I was running low on coins (on one of the rare times I could actually catch the flash balance), I pressed the button to buy more, and had 2 coins deducted form my account instantly. Of course, considering muscle memory, that happened a couple of times. So, after a few messages explaining the situation and not getting any recourse whatsoever, I called them out and they didn't like it.
