As promised, I am providing a link to the improved 1v43 firmware.
R26_1v43_no_random_MAC.zip
This is the original firmware in which I disabled random MAC. If someone uses Roon, after uploading to R26 you need to re-enable R26 in Roon Audio
To the question: why did they enable random MAC? I don't understand it at all. Normally this is used for security on public Wi-Fi, but these are devices operating on home networks, so...
When it comes to using Tidal connect on Android, the problem is with certificates. What Gustard shared in firmware 1v43 is the same as what I shared earlier. They didn't come up with anything new because they would have to pay for a certificate, so they used what can be found on GitHub. That's why it doesn't work very well.
