Dark Portal Broken across all my high level characters

All of my level 100’s to 120’s cannot access the level 60 version of the dark portal (Green one) They simply pass through the portal without being teleported. I have read about this bug for almost a year and had never experienced it until today. How can such a huge glitch or bug still not be patched or rectified? Put a shattrath portal in the portal room or npc to teleport you to thrallmar. I physically can’t access the outland. That entire zone is cut off from me. No transmog farming or anything else. Please Blizzard fix this.
