Not just you, I can't find it either 🤣

Hold my 1 sat/vB transaction, i’m going in
LOOK I USED A 69 PT FONT EYEBALL EMOJI TO SHIW YOU WHERE TO CLICK/TAP
You have to be looking a mempool block AND click/tap on the transaction visualizer thing, then it shows up. On mobile it’s pretty weird, probably better on desktop browser 
OK, found it - just in the "upcoming block" view though.
Thanks for reporting this issue. I've made an issue on GitHub to report this UX bug
