Halo 5 bug both legendary achievements not unlocking stuck at 80%

Hello, how are you? My name is Mateus. I'm an Independent Advisor and I'll be glad to help you today.

First, welcome to the Xbox community. I'm sorry you're having this problem.

Regarding bugs with achievements, what you can do to try to fix this is to clear your console cache as the instructions below indicate, and you can also delete your data from the console only, to see if the achievement unlocks. Usually, achievement issues are automatically resolved after a while.

*Solution 1:

You can also hard reset the Xbox console and its cache. Here is how to do so:

Step 1. Press and hold the Xbox button on the console for at least 10 seconds to open the Power center.

Step 2. Then unplug the power supply from your console and wait for 3 minutes.

Step 3. Plug the power supply back into the Xbox console.

Step 4. Press the Xbox button on the console to turn it on again.

Solution 2:

Go to your games and applications select 'Halo 5' and then click on it with the control menu button, select the add-ons and games manager option, after that go down to the third option where it says saved data, and delete these files only of the console.

*I hope this can help you in some way.

I soft resested the achievement yet it is still locked at 80% in game it says I completed it.

I understand, in this case, as the procedure did not work, just wait normally the problem is solved automatically, and the achievement unlocks in a few days.

achievements are just not unlocking for me at the moment, i have yet to see achievement progress to reset. I hope this does not happen to me. (although if it does, im sure MS can restore those). but i have about 5 achievements in the MCC that are just stuck
at "unlocking". A bit unfortunate as i wanted to play halo today. but if achievements a bugged, im not going to risk losing even more progress.

Pillar of autumn achievement not unlocking which is keeping my other achievements for completing the halo c/e on legendary arent unlocking either
