Hi Mitch -
Are you using the DS Lighting control app on an iPhone?
When looking at mine (Version 4.7, so not the most recent) and used to control an Aries Mini):
Select "Lightning setup" under Settings
From there, select "Lightning Device" (for me, it shows My Aries)
Scroll down just a little and find "Additional Operations"
Open "Additional Operations" and scroll down to near the bottom
Find "MQA Playback Setup" and also "Streaming Quality"
Under "MQA Playback Setup", is MQA Pass-through (to an MQA enabled device) selected?
Then, under "Streaming Quality" (for Tidal) is FLAC MQA showing or do you see FLAC Lossless?
Maybe somehow FLAC Lossless got selected instead of the FLAC MQA option.
Might be of use if you’ve not checked already.
