Umbraco.MediaPicker3 doesn't initially let me drag and drop mp4 videos

Hi, I’m experiencing an issue in Umbraco 13 where, at first, when I drag and drop several mp4 videos into a ‘Umbraco.MediaPicker3’ component, I get the following error: ‘Cannot upload this file, it does not have an approved file type.’

However, if I click the ‘Add’ button, it does allow me to upload the videos in that window…

The videos aren’t too large, and I have the ‘multiple upload’ option enabled.

Thanks in advance!
