I'm also having this issue. It also occurs with The Gilded Age S03E02 for me.

Looks like a change at Max .. with "The Gilded Age.s03e02"
it's the same that I get the "Movie Mode" after play for analyzing
(But the download does not start with this one either)

[code][Info]: "[WVMax]" license is NULL!
[Critical]: "[DownloadControlMax]" **** Get download Processed fail. The error is : 307[/code]
Maybe coincidence - but I was logged out
and had to solve a puzzle to log in again
I get HDR10 only in 720p (so perhaps the other Key >HD is the problem)
