I have noticed that the Chess.com game review is often incorrect. For example, it suggests the knight is lost in the position below, but the knight can clearly move to d6. It often makes other incorrect assessments. Interesting to see if other users have the same problem.
Assessment will depend on the strength of the review that was ran. Did you look at the Show Tactic or run analysis to see what it gives if Nd6 is played?
Found out the best line, from an engine evaluation standpoint was not to move the knight, instead counter-attack the bishop. So it's not a review issue; it's interpreting the best evaluating line.
Technically, the knight wouldn't be lost, as there's an even trade that happens.
Game review run on fastest setting is rather bad--not surprising given the speed it does the analysis.
If you do the normal analysis, you'll see the lines and evaluation changes over time.
