What's funny about this to me is that I tried to sign up for insta once and could never get past their automated ID check that would fire after signup despite using a real ID. (So never did sign up. I suspect maybe they just really don't want you using web on mobile devices but ymmv.)
On mobile, Meta absolutely doesn’t want you to use web. I created my Facebook account in 2004, deleted it in 2018 (Cambridge Analytica scandal), and later created a fake one just to use FB marketplace to sell things.
I will never install the Facebook app on my phone, so I use a browser instead. The experience is almost unusable. I can’t rate people. I’m not even sure if I can send messages. I can’t list things. The UI appears to support features that don’t work in practice.
No biggy because I just use a Firefox container and use my laptop instead, where the web version actually does work.
How you do you use fb marketplace without installing the messenger app?
I've tried that, but fb has stopped sending email notification of messages, so without the messenger app installed for notifications, I'll invariably fail to check messages on any kind of timely basis.
