Problem
The financials shortcut button disappeared after the upgrade, and you cannot see the job costing portion or do the progressive billing.
Solution
Disable the Hide financials permission
Open the project you want to view.
Check if the Financials tab is visible. If not, proceed to the next step.
Go to Settings > Employees > Edit > Permissions.
Search for the Hide Financials permission and make sure it is unchecked.

Save your changes.
Go back to the project and check if the Financials tab is now visible.
Note: You may need to refresh the page to see the tab.
Congratulations! You have successfully located the financials shortcut button in Projects after the upgrade.
