Question about my new Vision 4K

[HouseOfMu]

Hi,

I've just bought the Vision 4K and updated it to latest stable f/w, I thought I'd try that out before attempting to flash the new GUI Alpha.
I've previously owned a Dune TV101, cracking little box so I'm familiar with the UI, but I can see its been developed much further than what that had.

Couple of early user questions:
Although I don't yet have it connected to a 4K TV , that's hopefully coming in a couple of weeks  (Philips 65OLED936), so using it in 1080p via an AV amp (can only do 1080p also).

Problem with Plex
I use Plex on many different devices for myself and family, I installed the android app and it connects to the Plex server and the frontend all seems to be working fine, but it simply won't play anything I select, I just get a blank / shaded screen with the whirring buffer/circle.

Checking on the Plex dashboard , I can see the Dune box is a registered device, but it doesn't indicate anything playing.
All the videos I've selected work fine on any other device. 
Any ideas what the problem might be?

Assuming I can get Plex working, does it use its own player or the Dune internal player ?
Will I be missing out on the Dunes ability to use the DolbyVision engine/bells n whistles?

If thats the case, I may just switch to using the My Collection.

My Collection:   
Does it auto re-scan any network source folder (SMB) or do I have to manually re-index all the time? as one of my source folders is constantly having TV/Films added and removed, so if thats not the case, for that folder I might have to revert to just viewing it in Favs.
This is one advantage of the Plex server monitoring and auto scrapping the folders, so would be nice if it did that.

That's it for now, any insight to those question appreciated.

PS. Thanks futeko for the prompt delivery service.

Does this mean I've got a Plex issue or a Dune Vision 4K issue ?

Is there a log from either that I might be able to look at ?

I'll flash the Alpha f/w, to get the new My Collection GUI, see if that helps

hmm ok just updated to lates alpha 311021 and plex is now broken just sits at orange spinny

I was on the latest stable and it did that, updated to R18 Alpha last night and same issue.

On the plus side, the GUI overhaul looks decent.

If it was working, would the android app (Plex) be able to use the DV VS10 engine features or is that reserved for the internal Dune player ?

Does anyone have Plex working on latest stable or Alpha f/w ?

Thanks

What is the advantages of using Plex on a Dune HD player?

[HouseOfMu]

Because I & family have many devices that all use the same Plex Server, which provides a UI that we're used too and anyone of us can jump from one device to another (in home or out) and resume whatever was in progress.
It also has automatic folder monitoring / scrapping (of new video files) dropped into various folders.  My Collection doesn't seem able to do that.

However, as this Dune was bought to be able to play 4K in one place (lounge / home cinema) its now more of a nice to have rather than requirement.
But if it (Plex client) can't use the new Dolby Vision engine capabilities (HDR etc) then I wouldn't swap using the Dune just for the frontend experience.

I can't get Plex to play anything, so it's all a bit of a mute point atm.
