Hi @Daio76 ,
Have you noticed whether the app switches off when your screen goes idle? If so, please try tapping the Home button while you're listening to place the app in the background, as this may prevent it from pausing/stopping when the phone reverts to idle. Similarly, if you have Always on Display active then please disable it to see if this helps.
@Daio76 Hi, clearing the cache of the app ,sometimes solves problems with how it works.
Also check: access Settings/Applications and look for the LBC app. In Battery, check to have the Optimized and not Restricted option activated.
