The achievement "Sail the Seven Seas" does not work

This trophy isnt working on the ps4 too.

I have gone to alot of ocean biomes and the progress bar doesn't change is still at zero and I even try a new seed if is wrong with that seed but nope

For some reason, I made the achievement again and it worked (the progress bar doesn't really change).

This achievement isn't working for me either. I hope they fix this.

I have tried everything under the sun to get this one too and it does not track any progress. I have completed every other achievement but this one won't let me (bedrock on Xbox One S). Minecon/Minecraft Live is bigger than the super bowl at our house (family of 7) so we take this very seriously, and it hurts not being able to complete it.

"legacy frozen ocean does not naturally generate, though it can be generated using a biome editor or add-ons."

I also have this problem. I used a full achievement map, and it doesn't work.

This achievement works as of the latest 1.20.71 test

I just got the Achievement! After a lot of wasted time and lots of experimenting, here is what I did to trigger it: I made sure to update a chunk inside each of the 9 ocean biomes. basically you just need to swim down and break some seagrass or kelp to have the chuck become updated and the game recognizes that you've been there. Here is the seed i did it on: -1376268638242768351

I have visited ALL ocean biomes within multiple seeds as i initially thought it was just a world issue. I have boated through them and swam down deep and broken seaweed to try and get the achievement.

I have hours into trying to accomplish this achievement with no progress.
