Hmm, I don’t use the feature frequently, but it hasn’t failed on me. I can say that I use CarPlay frequently, and Tidal’s CarPlay implementation is a thousand times more reliable than Spotify, so when it comes to device based implementations they seem to have done a great job.
Looks like they offer a free trial, https://offer.tidal.com/ so I would say probably best to pilot it with that and see if it suites your needs
EDIT:
Testing on my app, it doesn’t seem to do what you want to do. You can select different output devices seamlessly, but you can switch between two clients the way Spotify can, sorry for the misunderstanding. Hope you find something that works for you
