Apps linking to incorrect Facebook account
So I’ve been having issues for a few months now of trying to connect apps to my Facebook (like GroupMe or McDonald's) and whenever I did, it would automatically try to login/connect it to my best friends Facebook, who’d logged into Facebook on my phone ONE TIME and I never saved his info!
after scouring the help forums, I FINALLY found the help from a 2019 answer!
he was still logged in via the safari web Browser!!! Which I never use! I use google (i know. Apple iPhone and I use google chrome, don’t hate me)
so if you’re having issues with getting apps to connect to YOUR Facebook after someone else logged into their Facebook one time on your device, check your safari web browser!!!
