John F Wu @jwuphysics.bsky.social · 26/09/2026Thanks for the heads up. I tried a possible fix, but I'm not sure it'll work -- there are a few candidate reasons why iPhone and android might respond differently to short presses, so let's see if this lightweight solution fixes it.... 000
John F Wu @jwuphysics.bsky.social · 26/09/2026Are you on mobile? For me (Android/Firefox) a short tap will select the shown scaling relation (and change the data manifold projection), but a long press will show the mini pop up.
