I've timed a 10 HoA twice and not gotten the portal/FoS. What do I do?

More or less the title. I’ve beaten this dungeon twice, the first time with 15 seconds remaining and the second with a couple of minutes. Each time I didn’t get the Feat of Strength Achievement or the portal.

I checked my spellbook, it’s not in there.

What do I do?

It needs 2500 M Rating first. KSH requires 2500 M Rating then it gives you portal to each dungeon that you timed at 10.

wouldn’t be surprised if it still wants a 20 for portal because the blizz devs forgot to change it to 10 or something stupid like that.

That’s not how it’s been the previous seasons. Or even last expansion.
