For those hosting with Pantheon:

Pantheon has a known issue with DropzoneJS, which is used for the Media Entity DropzoneJS widget and Media Bulk Upload module.

The module does not interact will with multiple-container environments, such as Pantheon, and is known to cause issues within the platform itself, which is what the site is currently experiencing.

see Pantheon's documentation here: https://docs.pantheon.io/modules-known-issues#dropzonejs
