Same on Android. The UI on that page is very sluggish

Looks useful but am I the only one who experiences this UI as slow and janky?

Not sure what's your use cases, but I have never encountered any of issues youve mentioned. Never got any delay, everything works smooth. I do use it a lot on desktop and mobile

Definitely slower loading and jankier scrolling on my phone.

It lags pretty bad on my Pixel phone too..

Same on Desktop tbh, loads way slower than my scrolling!

Looks good but runs extremely slow on my phone (LG G2)

I'm using it and it's very slow and looks and behaves like some weird iOS port.

Slow on what hardware/OS? It's instantaneous for me on Mac, but can be painfully clunky on iPhone.

It kind of freezes up on my phone. Not intolerable but definitely slow.
