Facebook auto logged out-turned on location when I logged in again.

So we’re at my buddies house. All of a sudden my gfs Facebook logs out. Then mine and my friends did too. Those two were able to log in with out a password. I was not.
Then a friend of ours posted on there with a question and asked if anybody had the same happen. When the GF was reading the comments... one or two mentioned that their location was now on. So we checked. And 2/3 of us it was. It seems that it’s all iPhone users that we can tell? But not sure on that pet.
Then another person commented. They were asked to provide info from their DL like address and DOB. Just a heads up.
If I’m asked for personal info I’ll be departing the FB world.

Check your location settings.
