Every single year-2021 post that I made on Facebook has been suddenly deleted as of today or yesterday (that is, posts made by me, on my own wall). I certainly didn’t delete them (they were important posts that I needed to be kept,) nor did they contain any content that could have possibly resulted in violating any Facebook rules. What kind of glitch could cause this?
Don’t know what caused it. Just throwing out another data point: it happened to me, too, and I verified with my friend that she was seeing the same thing. And then it came back.
