I keep switching between v3 and Old Chess.com because v3 can be glitchy. It's a work in progress. Share with us their response.
I'm very excited about having Chess960 in v3, BUT I still haven't successfully been paired with anyone a single time. Maybe it would work better if 960 had it's own preset button, and only one time control to choose from for 960. Kind of like how chesskid.com only has 15 minute games so people are paired together faster.
