Let's have our Tech team take a look. To keep your information secure, please complete our request form at aka.ms/Minecraft-Support so we can quickly and safely assist with your question! ^BT

Can you tell me how long it will take to review the issue?

Can't give an estimated time, sorry to say, but I assure you that an agent will reach out to you as soon as they can. Thanks for your patience in the meantime! ^BT

Your support agent answered me, but on the wrong topic. I'm still waiting for the achievements to be completed on the other phone.

If you are chatting with our support team and don't have a ticket number yet, please keep working with our team members there. If you still need assistance, reach out again when a ticket number is sent to your email. ^IV

After the recommendation that I was given, all the worlds disappeared from me. I made a copy and now I can't restore it. Release 1.19.63

If they disappeared, reach out in the ticket and let the Agents know so they can help you with this. ^BT

Hello, I restored the worlds, but for some reason the achievements still do not work. What to do?

Glad to hear it! IF there's still something missing, I'd suggest letting the agent know in the ticket and they should be able to help you with that too. ^BT

They can't help with achievements. They say to report the bug to the bug tracker.
