Hi,
just looking at Grey Arête (HVS 5a) (hoping to do it this weekend). I'm running Brave on Linux: Version 1.26.67 Chromium: 91.0.4472.114 (Official Build) (64-bit)
The grade voting box on the right of the screen seems to show a mix of technical grades, not in any particular order starting with 9b+ at the top, and working down with a certain amount of randomness (e.g. somewhere in the middle it goes ... 6b+, 5b, 6b, 6a+, 5a, 4c, 6a, 4b ...).
DM me if you want a screenshot - it looks like a bug from this end.
Cheers
Steve
