Odoo POS Balance Update Fix

I'm experiencing an issue with the Odoo Point of Sale system. The balance (Amount Due) on the customer invoice/receipt does not update in real time. It only refreshes after I close and reopen the POS session, which is quite inconvenient.

Key Issues:
- Balance not updating during transactions.
- Affects both cash and credit card payments.
- Occurs on an unspecified version of Odoo.

Ideal Skills and Experience:
- Expertise in Odoo, particularly POS.
- Strong troubleshooting skills.
- Experience with Odoo updates and balance synchronization.

Looking for a solution that ensures real-time balance updates.
