An example: https://www.chess.com/puzzles/problem/1003132 (hopefully it appear the same to you as it does to me)
It starts with "White to move". When clicking on 'practice vs computer' and an new tab/chess opens you will see the puzzle starts as a copy of the puzzle but with black making a new fist move on top of the previous start position before its "white to move" again.
When playing Puzzle Rush Survival Mode and you fail at a puzzle, there is the option of clicking on that very puzzle to practice it again. Sometimes you get to menu of; ‘play problem’ again, ‘show solution’ and ‘analysis’. This is best as I can then redo and figure out the error.
However, sometimes I don’t get that menu but instead one option; ‘Solve it!’ which when clicking ask for premium subscription to continue. Okay, chess.com need a selling point for subscription. Below that button there is those smaller ones (setting, comments, download, share and practice vs computer) and when clicking on the ‘practice vs computer’ the puzzle begins again, BUT, it does not start with the correct move order. When a puzzle is presented we see the last computer move and then it is MY turn to move. While after clicking on the practice vs computer mode the puzzle starts with the last computer move counted inn and then suddenly the computer makes another move on top of that, which makes it a double computer move. Instead of black-white-black-white moves, it become black-black-white-black moves. Basically it copies the puzzle with the first auto-move included and then begin with a second new “first auto-move”. Does my explanation make sense? I wonder, how can this be corrected or avoided?
