After a typical Tesla long wait, Tidal due out with next major release, 2021.40.x, although this release seems to have stalled so only limited general release so far.

No sign of MQA, although those reporting probably do not know what to look for, but wishful thinking that maybe a third party got involved... Not sure about masters, or even if it is an option, but HiFi only when connected to wifi (or tethered to a phone). Can be downloaded though.
