[Can’t Netfile dt income from multiple jurisdictions]

I had the same issue mid March . Helpdesk told me to update the program and failed to respond after I reported that this didn't work. I then looked at the CRA website listing of tax software certified for Netfile for 2023 returns. It stated and continues to states that Form T2203 is not supported by UFile for the 2023 taxation year but adds "Certification in process" without any indication of the timing.

Thanks Hollyjean. I have only recieved an automated response to my support request.

I had the same issue today. The T 2203 was removed from the list of Netfile exclusions several years ago and I have been successfully filing with UFile since then until today.
