I put in a trouble ticket with Tidal and here was their response (or lack thereof)
"When launching Tidal, my MQA parameters are missing in the streaming settings. Also, my collection is no longer showing MQA for my favorite tracks and albums. What’s up with this?"
Response from Tidal:
Thanks for getting in touch with TIDAL Support.
We have received your inquiry about the sound quality reflected on your account and we will be glad to assist you.
TIDAL has always prioritized and invested in superior audio quality. Our commitment to open platforms for both artists and fans drives our adoption of FLAC, and specifically HiRes FLAC as the preferred option for the best sound quality we offer.
You will see an updated audio quality settings screen on iOS, Android, Desktop and Web. This update makes it easier to choose the right audio quality for when you’re at home with a WiFi connection or on the go using a data plan. The formats available on each quality level is below:
Max* – High fidelity lossless audio up to 24-bit, 192 kHz with HiRes FLAC (Free Lossless Audio Codec), an open-source format that every artist can create and deliver their music in, and Master Quality Authenticated audio (MQA).
High – Lossless audio with FLAC (16-bit, 44.1 kHz)
Low (up to 320 kbps) – Listen to the music you love using lower data usage with compressed AAC files.
In addition to utilizing MQA, we make use of various high-quality and immersive audio formats, such as Dolby Atmos, to provide our subscribers with a premium listening experience and more artists the opportunity to share their music exactly as it is intended to sound.
If you have any other questions, please let us know.
