Minecraft Won't Save Progress If I Am Playing Online. How Do I Fix This? (PS4)

I am talking about both actually.. I know the Story won't save but how come the progress I made in GTA Online (Xbox One) did not save in GTA Online (Xbox 360)??

The game is Halo: The Master Chief Edition on PC from steam, but I had the same problem with Minecraft: Bedrock Edition on ps4.

I am seriously not sure how to even unlink it. I accidentally did the wrong email completely. Now it won't let me undo it or even unlink that account. It is just saying " We tried to gin you into your Minecraft account, but something went wrong." And I
don't know what to do to fix it. Can someone tell me step by step how to get this undone?

You won't lose progress or games or anything since saves are stored online if you played online.

This is the problem we understand it won't let you save progress. Your not listening to us. When we linked the account with our child's account. Now playing on the same exact account it won't let us create another Xbox live nametag because on the other
ps4 it already has one. Also when we try to create a different account on the ps4 so we can have separate gamertags it will not let us create a different account because it keeps saying it's linked to another account. We have tried to unlink all of the accounts
to fix this issue and it unlinked them just fine. But now we're stuck in a predicament because on all of the ps4 accounts we have unlinked, we're not able to play Minecraft at all on none of the accounts, I do not understand why Minecraft has to have Xbox
live, Microsoft and mojang just to play the game. Somebody needs to fix this issue because we'veput our money into this game and not only we've lost it all but now we can't even sign into the accounts to play because it won't let us!!!!!
