Geometry Dash: Having Problems

I am having several problems with geometry dash (update 2.0). The game starts up just fine, and I don't have limited access to the game, but whenever I tap the profile button, it always says "something went wrong...". If I hit the refresh button, then weird stats will come up. They are: 88 Stars, 20 Secret Coins, 0 User Coins, 0 Demon Levels, and the basic icons with red and blue. What's wrong, and what can I do to fix it?

Also, a while back I made an account. The problem was when I posted a level, the last letter was cut off. So, I changed my username, but my shown username was still the same. Any idea why?

I know I'm asking for a lot, but I would be grateful for any help. Thanks in advance!

I know the answer only for the not changing name.

It happened also to me, and I think it is normal. You have just to wait a bit (2 - 3 weeks) and it will fix itself. That means you probably already have your name fixed. If not, then I don't know any other solutions.
