One account was listed as Facebook and the other Facebook 12xxxxx (random string of numbers). Could it be an app that uses Facebook login or a PWA? I’m trying to clean up my phone and want to remove things I am not using. Thanks!
I am on android 11. Today I went to the Account & Backup > Manage Accounts to change a sync setting on my email. When I was there I noticed that Facebook was listed twice. I only have one account and clicking on it didn’t give any details.
