Game version: latest
ios version: 11.2.1
iphone version: 7+

Problems:
1. can not invite friends through facebook share, game freeze in loading page
2. game freeze after online race, may or may not give reward
  2.1 player leave during race, result in game freeze after finish
3. can not test drive, no response on button

2 is the most important thing that should be fixed asap, or it is only a unfinished track running simulator
