And the new Facebook interface has killed off a number of features or wrecked them - these are features that relate to managing groups. At the moment it is still possible to revert to the old Facebook when managing a group, so perhaps they will fix this.
One thing you can do to improve Facebook is to click the top right button, then click Display preferences, then select Dark mode. This makes it darker so it hurts less.
Facebook is still an example of a horrible user interface. But it makes lots of money so what do I know.
