Hello 𝕭𝖑𝖆𝖈𝒌 𝕮𝖆t, thanks for posting we currently have some other threads open about this so I will merge your post together.

There can be up to a 24-hour delay for the Connect launcher to register a challenge as complete.

Have you tried waiting 24 hours after objective completion to see if your challenge is then synched as complete in the launcher?

A few players have gotten back to us and confirmed this was the case with the weekly challenges, though I know there are some problems with battlepass challenges progression, ongoing right now.
