Can we change our update times?

Hi, you can change it without cost once. For the next change you will have to pay with money. (Not points)

But You can make it like we can change our tag once a year or 2 times per year if we want to change more than 1 or 2 we pay money

Hello DF DreamDemon,

We use the billing email for your account to send emails. You can change this information by going to the commerce page at (https://account.microsoft.com/), selecting "Edit your billing info", and then changing
your billing email from that screen. If you have only recently updated this information, it can take some time for our page to update.

so we are all clear then, Facebook changed it and it is now impossible to use Facebook to sign in? Or MS is choosing not to update the app to accommodate the change so Facebook has made?

And if we can no longer use Facebook to log into the app, is there a way to transfer our stats/game history to our MS account?

Nope, there is no way of changing it on the app. I hope they update it again so we can edit our profiles and send pictures to others also.
