Qnap TS 251+ DLNA issue

[Enquiries]

Hi using DLNA on my Nas to view photo Album I have created. I use my android 4k Sony Tv to view the photos Via Sony built in media App, using the DLNA process, If I Add a Picture or Album to the Nas through Photo Station the Sony TV does not see the Picture or Album. I have restarted the DLNA and Reindexed, But still the photo or Album will not show, even after a week.. All I get is the same Albums , Video , and Music files I started with. It seems as though the DLNA file is not being sent to the TV. Is there a way to force the DLNA file to be send? Note:if I change the name of the Nas server the TV see the change. but no change to the photos I have tried using Qnap Android version for Sony Tv but the user interface is rubbish and will not give full screen in pictures. but this uses SMB which works Ok. your Help would be most welcome kind regards

This is unusual. You should open a support case with Synology.
Alternatively, you can install Plex. It also comes with its own DLNA server.

I hope this helps.
