There have not been any recent changes to the process for updating Budgets by Location in QuickBooks Online, Lauhanwee.

May I ask if you've created a Subdivided Budget and are trying to update its location on the Budget page? If so, I recommend clearing your browser's cache so the system can start fresh. Also, ensure you're using a supported browser to avoid compatibility issues.

Once done, update your Budgets by Location again to see if the issue persists:

1. Go to the Budget page located in the left panel.
2. Locate the budget you want to edit, then click the arrow drop-down.
3. Click View/Edit.
4. In the Add subdivided budget for field, select multiple locations so you can change the location in the View budget for field.
5. Then, change its location according to your preferences.
6. Select Save.

Also, you can assign classes to your budget to represent meaningful segments in your company, see this article: Set budget targets for each class in QuickBooks Online.
