From real experience
When encountering issues uploading documents for a UK visa application on the official portal, try these solutions: disable VPN, use Mozilla Firefox browser, attempt upload from a mobile device using cellular data (not Wi-Fi), or tether mobile internet to a computer.
Clearing browser cookies and using incognito mode may also help. Some users find success by accessing the portal late at night. Ensure to save each uploaded document immediately. Document uploads and deletions are typically allowed until 23:59 on the day before your biometrics appointment.
