I was logging in to get my free Deep Sea mash up pack, today (1 June) but it didn't work. Steps to reproduce: (1) sign out of your Xbox live account. (2) log back in to your Xbox live account. (3) go to your marketplace packs (to see whether it worked.) I haven't received it after 12th of June 2019! Mojang, please fix this!

I am having the exact same issue, I tried logging out of my Xbox live account and logging back in but the pack still didn't show as free.

In the article, it says "your free map will be accessible approximately a week after in your account in the Minecraft Marketplace, on (or before) June 12, 2019."
Not really sure how this happened
