Steps to Fix Dataverse Version Mismatch
Check Environment Version
Go to Power Platform Admin Center → Select UAT Environment → Check the Dataverse version under Settings > Updates.
Compare it with your Dev and Production environments.
Trigger a Manual Update (If Available)
If an update is available, you should see an "Update Now" option in the Admin Center.
If not, the update may be rolling out gradually in your region.
Verify Deployment Schedule for Your Region
Dataverse updates are rolled out in phases across different regions.
Since you're in the UK, check if your UAT environment is part of a different deployment wave than Dev/Prod.
You can find more details on Microsoft’s update schedule here.
Create a Temporary Dev Environment for Testing
If UAT is stuck on an older version, consider creating a new temporary environment with the latest Dataverse version.
Import the solution there to verify compatibility.
Contact Microsoft Support
If your UAT environment should have received the update but hasn’t, raise a ticket with Microsoft Support to request a manual update.
