Unsupported Browser on Wordpress.com
Logging in to Wordpress.com in GNOME Web 41 from Flatpak results in a page called "Browse Happy" that says I need a different browser.
This made me unhappy.
The options are to continue anyway, or learn about supported browsers on https://browsehappy.com/ which implies that not using a "GAFAM" browser puts you at risk on the web.
