Amazon Mubi : license is NULL!

[Willimoon]

After cancelling a list of Mubi video downloads (from Amazon Prime), I can't restart the download which ends in failure. All the videos in the list are affected and end in failure.
However, from the Amazon Prime Video for Windows application, I can play the videos or download them.

Thank you for your help
