WD My Cloud Video Thumbnails Twonky 8.5

Hi could you please advice what I can do to fix the problem I am having with
video thumbnails not showing for videos.

I have recently updated my WD My Cloud Twonky to the latest version (8.5)
and purchased the licence key. Everything is working fine except I cannot
get the thumbnails to show for video clips.
This was working fine on my old version (7.xx) but I could not play videos
which had been recorded on my phone on my Samsung Tv, this was the reason
for the upgrade.

I have followed the below document from your site but I am still unable to
get this to work. Most of my files are mp4 and like I said this did work on
the previous version.

Thanks

Where did you download Twonky 8.5 from, was it from WD? Which generation of My Cloud do you have, 1st or 2nd? What document did you follow? You did not provide a link.

You may want to look at this from the Knowledge Base.
