In my haste to release 2.4.0 before the holiday break, I forgot to include the changes I made to the "No closed captions found on media comment" error. You can view the 2.4.1 release notes to download this version of UDOIT.
I'm the Team Lead of the Techrangers, which is a group of part-time students that specialize in course development and software engineering. I'm also the project manager of the UDOIT tool, which is an open source LTI that scans courses for accessibility issues. Check it out at https://cdl.ucf.edu/udoit
