Due to the changes to Apple, Google and other big tech company policies, Facebook has been logging out users.
The tech companies are keeping your information more private, and because of these policy changes Facebook is unable to check cross device to ensure it is you.
When using Facebook on your computer (especially while using FriendFilter) DO NOT USE YOUR MOBILE DEVICE
Because of the policy changes, using your mobile device on Facebook at the same time on a desktop can send up a red flag with Facebook.
This has nothing to do with FriendFilter or our privacy, your information is still very safe on our platform.
The issue is that Facebook thinks that the computer or mobile device is someone else accessing your Facebook page because you have two sessions going on at once.
Please do not use two devices on your Facebook page at once, especially while Facebook is sorting out how to check cross device to ensure it is you.
