Fallout Shelter achievements have stopped progressing

so after no playing Fallout Shelter for a few months due to my achievements not progressing, i thought i would download and try again, and i still can get them to progress. I have 5 left and 1 says locked on my website profile but, the other 4 haven't changed,
i had complete 60 quest and 100 quest in which I've done a lot more then that and counted yesterday, 50 raide attacks I'm pretty sure I've done that as well, make 25 dialogue choices and I've definitely done that. The locked one i have is get a dweller from
level 1-50.

I've tried resetting console and tried a lot of fixes in the forums but, nothing os working.

Achievement Progress Stopped Fallout Shelter

Back in February I started the game Fallout Shelter on my PC, the Win10 version. I also played it on the xbox one occasionally. I was playing through and progressing through the achievements well but noticed a few of them stopped progressing. Specifically
three, "You're fired" kill 10 enemy bosses, "Enemy of the wastes" kill 500 enemies, and "Higher and higher" have a level 25 dweller. There's no stat counter for bosses but the progression percentage has been at 30%, just today while playing I killed 4 in
two different missions and no change, it's not a rare occurrence. There is a stat for wasteland enemies killed and I have over 12,000 but no achievement. I have the level 50 achievement and have probably close to 100 over level 25 gaining towards level 50.
So the game registered the level 50 achievement but not the level 25. I originally reached out to Bethesda support thinking it was bug with the game and tried the few things they suggested but they ultimately came to the conclusion that it was a problem on
Microsoft's achievement tracking end and not a problem with the game. They suggested I delete the cloud save and see if that cleared the cache and forced both platforms to recognize the same save and the tracking would start, it did not. They suggested deleting
and reinstalling one or both games, nothing. They suggested only playing on one platform with the same save, nothing. The only thing else I've read on other forums is to start over. This would forfeit all my progress towards the final achievement I need
to have 20 legendary dwellers which I've spent real currency trying to unlock due to you not being able to get enough without buying the lunchboxes. I am willing to try anything again to try and fix this. Some have said they have popped randomly but it has
been over 6 months without playing and no update has come out to fix the issue and mine did not randomly register.

 

Hi

There is a guide here to help unlocking stuck achievements, not sure if you have seen that:

Achievement Unlocking Issues? -- CHECK HERE!!

I have heard that the game can be buggy with achievements, but that is possibly a developer issue.
