Percentage of mp3 vs FLAC on Tidal?

Yes I would love some examples also I have not encountered any mp3s in about a year of streaming Tidal.

The source that I'm using is a Squeezebox Touch - I did find some information stating that when Ickstream was being used the app would indicate that a file was an MP3 incorrectly when it was really FLAC coming through - I'm using the newer Tidal app for Squeezebox but it could be a similar glitch.

For example, I clicked on almost every Bruce Cockburn album that was in Tidal - 2 titles read as FLAC 1 of which was Stealing Fire, pretty much everything else read as MP3.  The National Cherry Tree also read as being MP3 but other titles in their catalog were FLAC.

It sounds like there is either an issue with how the Squeezebox is streaming or it's incorrectly labeling FLAC files as MP3 - my understanding is that all of the work that's been done for Squeezebox has been by end users as of late including the Tidal app I'll poke around and see what I can find out...

I have been going round and round with Logitech and Tidal trying to get my Squeezebox to play Tidal in the higher quality format. Yesterday was great I had no buffering issues and listened to music for almost 2 hours. Today I am back to buffering every 20 seconds.
Tidal tells me that the software technology was worked out with them by Logitech. Meanwhile Logitech has pushed me to tier 2 (support???) with none to little feedback. After hours of tech 1 support. I have three emails sending them to the FAQ on their support page and asking me to restate the issue. I have 100mbs stream and all other apps play fine. Any suggestions folks? I am frustrated! Thanks.
