On Android: App settings > Jerboa > Set as default > Supported web addresses > check whatever you like
I checked my instance’s only, so whenever I click some link to a community in Jerboa it I will go directly to the community, instead of it opening in the browser.
Don’t think it will work very well with other instances, right now tho. At least not until link redirection is launched.
All the lemmy meta TILs are going to be popular for a while
