Let me share my experience with Volumio and Tidal and hopefully it can be of help to you.
I tried MyVolumio for a couple months because of the “native” integration but after realizing how painfully bad it was I decided to cancel the subscription.
It was much better to use bubbleUPnp and simple direct stream to Volumio without requiring a subscription which I found not worthy. Yes it was limited to 44.1-48khz but it simply worked well and was very inexpensive.
I had great expectations for the Tidal Connect implementation and waited for it anxiously, finally a way to stream from the Tidal App at high-res.
But what a disappointed it was. Due to Tidal license model it does not stream beyond 48hkz. For that you need a MQA capable DAC and to be honest I’m not convinced of that marketing first technology.
It’s a fact MQA is not a lossless format and it’s simply a marketing gimmick by Tidal to make money in detrimental of music.
So I gave Qobuz a chance and what a wonderful surprise it’s much much better than Tidal in all aspects.
It streams Flac up to 192khz and is true lossless and you can stream from bubble upnp to Volumio without a subscription.
So, my advice is that give a try to Qobuz and stop using Tidal. Tidal is lying and abusing with MQA.
