Email with more than a 4meg attachment stuck in Drafts folder with Modern Auth

With the demise of basic auth, the Dex Mail functions no longer work for MFA. To send emails, you need to call the MSGraphEmailSendEmail of form syEmailObj script, so that the Visual Studio add-in will fire, and send the email via Microsoft.Graph. Initially, there was a 3meg limit in 18.3, but that was noted as being fixed in the 2021 year end update. However, attachments larger than 3meg still get stuck in the Draft folder, without attachments, yet the script says it was successfully sent. The emails never go, and you have no idea that an attachment is missing.

Has anyone else run into this, and figured out a way around it? Short of writing something that would split PDF files on pages to be under the 3meg limit, and then sending multiple files spread across multiple emails (which would be a lot of work).

Thanks,
