I posted this issue today, but it was incomplete and missing information; so i'm gonna tell my issues with some achievements on the Windows edition of Bedrock. Well, first of all, in the Mojang site saying about achievements, they mention the awaiting of 24 hours to the achievement to pop-up, and some possible fixes to it. But I did all of what they were saying, and it did not work. The achievements which are most bugged are: Archer, Map Room, Sniper Duel, Sound of Music and Sound the Alarm. All of them were tested in different worlds, multiple times and did not work. And as I said, I already did all of the troubleshooting steps:

• Make sure you are connected to the internet and that your game is up to date - Done.
• Restart the game and your PC - Done.
• If possible, reattempt the feat that gained you the achievement - Done.
• Back up your save data and uninstall Minecraft and reinstall it on your system - Done.

If possible, we all, Bedrock enjoyers would like a major bug fix to the achievements, if that's possible. Thank you.
