What is general game centre error

[support1]

Please login in “Game Center” app first and then login your Haypi account “General”-> “Management”-> “Game Center”-> “link”, otherwise it will display “general game center error”. Please note that only one Haypi account can be linked to Game Center.

I am logged in and I have nevr linked my account to any game centre before my game centre is also not linked to an hapi account

If you've created your account on game center...go to Haypi, go to General > Management > Game Center (located at the very bottom of Management) then link your account. Make sure the account you link is your main because it says you can't link more than one account.
If you haven't created your Game Center account, go to the Game Center app and make an account, then do the above.

I linked my main account and went to an alt and it said it was linked on the other one to and i was able to access acheivements and everything is this a glitch or am i reading something wrong

Both accounts are linked? Or just your main? I read it as only one could be linked, not both.

Yeah i thought so too but apparently not as far as i have seen
EDIT:I have realized that it only shows the acheivements of my main account but it says i'm linked to my alt until i log onto my main so i guess it is a minor glitch
