I wrote a ticket 10 days ago about the same problem but got no answer so far, forum doesn't seem to help either...
https://www.chess.com/forum/view/help-support/how-do-i-retieve-a-saved-self-analysis-from-a-finished-game
It shouldn't be that hard to retrieve a single pgn but now that I know for the future I plan to work elsewhere, peraphs if you won't need too many analysis making private studies on lichess could be an idea(even though switching back and forth it's a pain). I'm waiting to get an answer from a ticket Isent over 10 days ago, I've sent another one yesterday I hope to get an answer soon. I'll keep you updated as soon as I'll get an answer.
How can you review your analyzes during the game? At the end of the game, clicking on the analysis button, even if you see the red asterisk that indicates the presence of your own analyzes, you are no longer able to enter the correct screen and the chess.com analysis engine starts automatically. I want to be able to review all the MY analyzes I did during the game. It is a job that is lost and I don't understand why.
Below is a game in progress, so DO NOT COMMENT ON THE MOVES. THE POST DOES NOT NEED TO HAVE SUGGESTIONS FOR THE GAME.
When the game is over, I no longer find a way to review everything I have analyzed.
