SinSinCos Setting up the app, depending on the system on which it is installed, can indeed be a bit complex without a minimum of knowledge, but once set up, it is pure pleasure to use.
The only real drawback is that sites change their architecture from time to time and the app has to be updated (which can sometimes be time consuming).
But in the absolute, the app allows you to completely free yourself from dlna and smb and allows you to make your own local streaming server (or even online if you have a good internet connection and you configure the thing).
For questions, there is the xbvr discord which helps.
