When I try to log in through Facebook in Call of Duty Mobile using an iPad it shows "Your...

if its giving you sorry please try again then its very likley that your entering the wrong email and password. You should be entering the email and password used for your facebook account not microsoft when trying too link. Try loging out of facebook on
a computer or mobile decvice then log back in on the same device with the infomation your using on xbox too check its right.

A other option you may want too check your premissions on your facebook settings/privacy on facebook itself too make sure there not blocking 3rd party connections or links. Has it be used too find facebook friends on xbox it needs premission too use your
facebook info and search like a mobile app premissions does

Solved it.

I went on the Call of Duty website, and unlinked my Facebook account, then deleted Call of Duty from my app list on Facebook, then relinked my account through the website, and now all is well.

Hi Yahia

Sorry to hear about that, however, when you play on iPad - when that specific "Microsoft account" logs in to your iPad, and purchase things off the Marketplace, you will be charged through your Apple account/Apple store. So technically, the purchase would not reflect on the Microsoft account that was used. And at this point, there's no way to confirm which account logs in to your game to purchase off items unless you try and check all your accounts one by one.

Is your iPad up to date Jake?
If not, could you please try updating it?

Or try using a different device (like an android phone or an iPhone, in both cases using mobile data)

My ipad is up to date.

I have a phone, but i’ll try it.

I think that its just so you can log into ELITE from Facebook. To verify your Facebook account, you submit the info you use to log into Facebook. Having said that I went to link my Facebook account to ELITE and it still says 80%, yet when I scroll down
it shows that I have link my FB account. My guess is its just another bug.
