The default page for Friendica is the 'Network' page (https://friendica.world/network), but that loads very slow, almost always getting into a time-out.

Going to other pages mostly works, for example https://friendica.world/community

I have now enabled the 'Startpage' addon, where you can set the page you want as the default landing after logging in. I have set it to 'community'. You can change it here: https://friendica.world/settings/addons
