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)
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.
