How do I view an entire instance thru mobile app?

Let’s suppose I want to browse lemmy.ml or lemmy.world. This would be similar to viewing the website lemmy.ml through a browser where various communities are visible.

However, on a mobile app, I’m unsure of how to achieve this. I can only see specific communities, such as [email protected], for example. I wish to view lemmy.ml in its entirety.

When I select ‘All’, it displays all instances instead of specific ones.

Could anyone assist me with this? The apps I’m using include Jerboa, Connect, Sync, and Voyager.

Thank you in advance.

EDIT: Only Connect can do this as far as I know. I can GUEST login to different instances like lemm.ee and browse them.

Both Jerboa and Sync does not have this functionaly. I haven’t tried on Voyager yet, I only use it when I’m on browser.
