So when you go to wefwef.app, which is the official instance, you can have your browser install the web app version onto your phone.
When I’m hosting my own instance, for some reason I don’t have that option to install the web app.
I’m using the same browser, same phone, same internet, same everything. The only difference is I can’t “install” my selfhosted version of wefwef.
So I had setup my nginx proxy to secure my self hosted version of wefwef by using basic http auth. I disabled it, and that fixed my issue.
