Looks like it will take some time to figure it out, but the developer ljdawson is looking into Lemmy support for sync.
This app is so smooth, and caching posts and comments for offline use while on the plane or in low reception areas is a clutch feature for me.
This is what I’m wondering as well, I don’t mind making a Lemmy account as well, but if Kbin compatibility is a feasible feature, it would really join together the two communities
