I haven't had an issue accessing Tidal all through this period that the problem has been reported. I rebooted my QNAP a couple of days before the first post in this thread to fix a problem I had with Napster. Tidal has been solid for me pretty much the whole time I've had my Sooloos system. I do have the issue of long tracks from Tidal not playing on Sooloos and it is one of the reasons I keep Napster around.
