if you use roonArc with two or more profiles it impossible that everybody finds it’s music. See my feature suggestion about Improved profile-based Library Seperation
So "recently added " is most likely not useful, as the albums from all profiles appear.
The other way to find music is thru the album list. But due to limitations in carplay the list ends early - i have like 4000 albums and i can roughly see 1/3 of it.
In Apple Music the albums are put in chunks … you can access each by hitting the “A*Z#” button and then pick a letter.
Or much better, there is a filter that only shows favorite albums. That filter even exists in the roonArc app… but it’s not implemented in the carplay front-end.
It’s seriously essential for my usecase that there is some improvement in those areas is done.
