How come some of my games don't show anything in the accuracy column?

Sometimes the accuracy numbers are available immediately after completing a game, sometimes they appear after some amount of time, but there are a number of games in my recent history which are days old and which only have an Analyze link.

Someone needs to analyze the game after you finish it to see those numbers. If you didn't do it, it might be your opponent. 

That's the thing that's confusing me, because I have run analysis on the game but the numbers still don't show in the list.

That happens from time to time. It is a bug. Sometimes you have to do it multiple times before  it succeeds.

Ah, that makes sense. Thank you.

The absence of accuracy scores in some of your games, with only a "Review" option displayed, typically indicates that the game analysis has not yet been performed or the results are not currently being displayed. Here's a breakdown of the common reasons:

Game Not Yet Analyzed: The most straightforward reason is that the game hasn't been analyzed by the Chess.com game review feature. To see the accuracy, you need to initiate the analysis.
Opponent Analysis: If your opponent has already analyzed the game, the accuracy might be available when you review it. Chess.com often avoids redundant analyses.
Temporary Glitches or Bugs: Occasionally, there might be temporary software issues or bugs on the Chess.com platform that prevent the accuracy from being displayed correctly. These issues are usually resolved by the Chess.com team.
Delayed Processing: In some instances, especially during peak usage times, the accuracy calculation might take a little longer to process and appear in your game history.
Browser/App Issues: Sometimes, clearing your browser's cache and cookies or restarting the Chess.com app can resolve display issues. In some cases, using a different browser or the app instead of the browser might help.
Account Type (Potentially): While less common, some older forum discussions hinted that certain account types might have had limitations on automatic analysis. However, this is less likely to be the primary reason now.
What you can try:

Click "Review": If you see the "Review" button, click it to initiate the game analysis. Once the analysis is complete, the accuracy score should be displayed.
Refresh the Page/App: If you have already reviewed the game, try refreshing the page or restarting the Chess.com app.
Check Later: If the accuracy doesn't appear immediately after review, it might be processing. Check back after a few minutes or hours.
Clear Cache/Cookies: If you are using a browser, clear your browser's cache and cookies and then log back into Chess.com.
Try a Different Platform: If you usually use a browser, try the Chess.com app (or vice versa) to see if the accuracy is displayed there.
