when tagging photo (P) or (X) on Lightroom, the white or black flag does'nt appear on the thumbnail

Please go to Help>System Info… and provide us with your software's installed version number. 

You posted that you are using version 8.3, which is not Classic, but later identified your version as Classic. We need to know for sure which version you are using.

Thanks!

Also @Sylvain1674 , which operating system are you using?

Hi @Sylvain1674! Welcome to the community! 

Just to clarify, are you talking about Lightroom (cloud-based) or Lightroom Classic? Could you share a screenshot? I assume you mean Lightroom since you mentioned you're on version 8.3, which is the latest version. The keyboard shortcuts for picking and rejecting flags in Lightroom are Z and X.

If you're using Lightroom Classic (latest version is 14.3), the shortcuts are X and P, and the flags do appear in the thumbnails.

Thanks a bunch!
