I used to have the forum app(I have no idea how), so I used it every time, but now since I switched computers, I can’t seem to see it in the app store. Is there a specific thing you have to do to get the app?
This forum uses Discourse, a free and opensource software application for discussion communities.
There is an app at https://play.google.com/store/apps/details?id=com.discourse&hl=en_NZ&gl=US however, the reviews suggest the mobile website (PWA) is wayyyy better.
I use the mobile site often, and it has everything I need.
