The War Within Season 3: Resilient Keystone 16

Currently bugged for me. Timed every key on +16 with 3 of them even on +17 and still do not have this achievement pop for me / still stuck at resi 15. I reported it to Blizzard and they tell me there is nothing they can do. I checked someone elses achievement and it seems my Priory +16 (timed!) did not count. Hope anyone else having a similar issue finds this, curious to know if it bugged out for others and which dungeon specifically didn't count. If it's multiple of the same like my Priory, this might help Blizzard pinpoint the issue.

Same, no response from blizzard after in game ticket or post on the forums. I was hoping it would have been fixed on reset, and it is not. Very disappointing.

Here is wha they said in the ticket:

Your ticket has received the following response:

Greetings Jon, Thank you very much for summoning me, I'm the Game Master Lorightyth. I came from the distant lands of Azeroth and I am in your presence to help you continue your adventures.

What I could gather reading your ticket is that you completed all Mythic+ dungeons within the time limit at keystone level 16 and did not receive the achievement The War Within Season 2: Resilient Keystone 16. I totally understand; these issues disrupt the gaming experience and immersion. Let me investigate what's going on here.

Investigating the issue, I can see that everything internally seems to be in order with the achievement system. In this case, I recommend checking the Wowhead article about this achievement. The War Within Season 3: Resilient Keystone 16<> />
If you believe you should have received the achievement but do not have it, as Game Masters, in the interest of being fair to all players, we cannot grant achievements to characters. Therefore, if you notice an error in the game, the best course of action is always to submit a report about the error in-game or on the forums, as each report goes directly to the developers who have the tools to fix and change things within the game. https://support.blizzard.com/article/000339262<> />
You can also report it on the Blizzard community forums, where you can see if other players have experienced similar issues. All updates on game bugs are posted there. https://us.forums.blizzard.com/en/wow/c/support/bug-report/17<> />
Before leaving, I'd like to thank you for taking the time to contact us and explain your situation. If you have any further questions or concerns, please don't hesitate to contact us again.

I’ve done exactly what they suggested, I have not heard a peep. Do better Blizzard.
