I didn't realize you were trying mobile initially. When I tried mobile, it also seems incredibly slow. My desktop didn't have this issue (when going from explore page to home). Everything seems a lot slower on mobile.
That is one of the slower pages on the entire app. I'd like to move that one to use an InertiaRails.deferred setup, so it loads instantly with a loading spinner - like you'd see with Suspense + RSC. (Hardcover founder here)
