Hi,

If a specific POS register is stuck on loading while others are working, here are a few things to check:

1. Check Previous Sessions:

    Go to Point of Sale → Orders → Sessions.

    Ensure there are no open/incomplete sessions for the problematic register.

2. Validate POS Configuration:

    Confirm that all Payment Methods, Journals, and Stock Locations are properly configured.

    Ensure no required settings are missing for that register.

3. Browser Cache & OWL Errors:

    Refresh with Ctrl+Shift+R or try opening POS in Incognito Mode.

    Open Browser Dev Tools (F12) → Console Tab, and check for any JavaScript errors (OWL component failures).

    OWL errors can occur due to:

        Custom POS modules or modifications.

        Missing images or product data.

        Corrupted browser IndexedDB cache.

    Try clearing browser Site Data (IndexedDB + LocalStorage) and reload.

4. Contact Odoo Support (Odoo Online SaaS):

    If the issue persists, raise a support ticket to have Odoo clear backend cache or check for corrupted data in the register session.

Hope it helps
