DTS Play-fi Apps für Wifi speaker in Iodé 6.1 Xperia 1 V

I have a set of Wifi speakers of Polk Omni series an Definitive Technology. They work with DTS Play-fi standart. I use to control them with the Play-fi app from DTS. There are similar apps from Klipsch, Phillips and Onkyo. I installed the app from DTS through Aurora. When I try to open it, the app tries to load “Ressources”. But it cannot finish it. I did set the block mode in the Trebuchet app to not block the app. Doesn´t change anything. It would be nice, to find a way to manage this.

Habe mal bei einem Redmi 8 /e/os installiert und die App DTS Play-fi ausprobiert und das ging direkt und ohne Probleme.

Curious if you checked permissions from System Settings > Apps > App to confirm that all permissions are enabled?
