OPT and COAX audio output

I encounter the following problem. Coaxial and optical outputs from Zidoo to an AV receiver, amplifier or other DAC have sound interruptions regardless of whether they are set in RAW or in LPCM2 format. Once every 10 -15 minutes the sound stops abruptly for one second. I play music with Tidal, Spotify, YT music, and so on. I have the latest firmware beta, 2.3.45. I read on the forum that this problem also exists with other Zidoo models. Does anyone know a workaround or firmware version that is stable?! It's actually annoying! And the Zidoo service does not communicate anything clear, concrete to me. Sounds like a kind of classical ballet to me
