@Johnny_Ooooops thank you for your question. There is a ticket here:
I was also in direct contact with @support, but at some point I just got the info that I should wait for a fix and there were no more responses. As I went lifetime in November 2022 I am quite dissappointed now.
I’ve been through my network, checked my Nucleus, checked my router, swapped switches, cables and stuff, worked with various endpoints, conferred with my ISP and had the line verified. Everything is absolutely fine from the experts’ point of view. But I have these long interruptions between songs. They are shorter after a core reboot, then longer again after a few hours. But they are never gone.
