How do I fix the error 349 when filing from TurboTax Business Incorporated

I am using TurboTax Business Incorporated 2024-2025 to file my company taxes for the year ending on 2025, May13. When I try to file, at the last step it comes back with a message in red letters saying "Error 349: You are currently using an outdated version of the Online WAC application.". I did update to the latest available version, 2024.5.5 Build 102. I've been using TT BI for the last 11 years without any issues...

Please help.

If anyone else gets this error, due to a change in CRA's procedure, you will have to call CRA directly and obtain the WAC. It's going to be like this going forward, until it changes...
