Misses vs Missed Wins


I believe, both the misses and missed wins are same. But, blunders are different. Blunder means a move that loses a complete material or it gives a huge winning advantage for your opponent.

The website should only show Misses. Misses replaced Missed Wins, but the definition also changed at the same time. The quick post game analysis, if you have that enabled, may not have been updated yet with the changes.

As far as I'm aware, the same is true for mobile, at least on Android.
