Does linking to FB take your coins and stats?

I started a club last summer, TikiTok. I keep wanting to link my account with / sign in using FB as they suggest, but then I get multiple warnings that I will lose everything when I do…

Is this correct??

If you have one account, just continue with linking the game. You won’t lose anything.

The sooner you link your game, the better in my opinion. But before linking, go to MENU, tap GUIDE and at the bottom is a Customer Service ID, take a screenshot in case something goes wrong and you lose everything, as it has happen to some. This way when you contact support they may be able to look it up.
