SharePoint
List view command set extension fails to load after the page is reloaded. Doing a "hard refresh" does not make any difference, but clearing all site data (F12 > Application > Storage > Clear site data) brings it back - until you reload the page and it disappears again.

Describe the bug / error
When you reload the page after first installing a command set extension the command set fails to load. The only way to make it reappear is to use the developer tools > Application > Storage > Clear site data and then reload the page.
This only works until you reload the page again - then it disappears again!
The console output while reloading the page (when the command set is not loaded):
Steps to reproduce
- Create the default hello-world Command Set SPFx: https://learn.microsoft.com/en-us/sharepoint/dev/spfx/extensions/get-started/building-simple-cmdset-with-dialog-api
- Open a list in the browser and you will see the “Command Two” button visible.
- Do a normal page reload and the “Command Two" button is not visible.
- If you go to developer tools > Application > Storage and clicks “Clear site data” and reloads the page, the “Command Two” button reappears.
- Doing a new normal page reload causes the command set extension to fail loading again.
Expected behavior
The command set extension should always load with the list view.
Hello,
We are facing the exact same issue with our SPFx solutions deployed across many different customer tenants. It appears to be a bug introduced by Microsoft with the "new" experience updates in August.
After researching on Google and in this forum, I found two potential solutions:
1st solution (confirmed that helped):
Change the "Offline Client Availability" setting to "No" (List => Settings => Advanced Settings). It seems this setting changes the list mode and prevents the use of "new" experience features.
2nd solution (unconfirmed):
Try updating the SPFx solution to use at least the SPFx 1.18 or 1.19 version libraries.
We have updated our SPFx version, but our customers have not yet deployed the new SPFx package, so I cannot confirm if this resolves the issue.
Hope this helps.
@SPJS is your list Syncing (in the header area where you see the list's name, you'll also see either a checkmark or a little circle of arrows)? When it's syncing, command set customizations won't load currently. You can set a list to stop syncing by going to the Lists App.
@reedpamsft Sorry If I confused you - I have two tickets open and thought I replied to the other one: https://github.com/SharePoint/sp-dev-docs/issues/9953
To answer in the right "context": Disabling sync does not help to keep the command set visible - it requires a hard refresh to stay visible.

@SPJS would you mind taking a network trace for this issue (the one being discussed in this thread)? This is not something I have been able to reproduce, except when Sync is turned on.
@reedpamsft It looks like it suddenly started working! I was preparing to do the network trace, but now I cannot replicate it again. I have done a lot of testing over the weekend where I had this problem all the time so I guess this must have been fixed already.
