I am baffled any time I’m on facebook how horrid it is. Loads insanely slowly, won’t accept picture uploads at random, randomly doesn’t let you share to people in your friends group (it will just hide people for no reason). Such a terrible website. Sadly I have to stay on it for friends and music reasons (there is nothing else anyone I know uses) but man, it’s crazy how badly they want you to install their spyware app so you don’t use the browser version.
You hit on the reason I suspect the website (especially mobile) is absolutely rubbish. To get people to install the app so it can spy on your mic and camera to harvest data for $$$. Jokes on them, it just reminds me why I deleted the app and reduces time I spend on the site overall.
