I can’t find a dungeon I have 22/23 and discover a area om Kehjistan, please fix it
You will want to post on the Diablo 4 Bug Report forum. “Fix it” is not helpful. You will want to describe enough that QA can replicate the issue. Tell them where specifically you are not seeing it unlocked. Also keep in mind, sometimes dungeons are behind Strongholds you have to do.
QA on the Bug report forums will not answer you, but that is how to submit bugs for fixing in later patches.
Make sure you complete all strongholds. Oftentimes a dungeon appears after you have defeated them.
