Yes, they made a deliberate shift to reduce the effectiveness of ’your’ posts so that you would then be forced to spend on ads to achieve the same thing. Prior, it was a level playing field, now it’s a dodgy lottery.

With all the earnings — a decent user interface would be warranted. Cluttered, disorganised mess — both front and back ends.
I hate it but am required to use it. Bring on the competition.
