For anyone cares, i'm working on this and submitting to Apple via my dev account bug reporter - i hope someone reads it, if anyone wants to add anything they've found, let me know.

Yeah, on me iPad 2 air, I cannot tap on artists in the 'related artists' sidebar when you go to an artist detail page. Reproduce it by: search for artist, tap artist, try tap a related artist. Will not work for me.
Also, Apple Music does not store what I add to my collection from Apple Music, no matter whether I try it from os x iTunes or iPad or iPhone (5s).
Apple Music on iPad also crashes, and before crash the UI often completely freezes to the extent where I cannot use the home button anymore! Like I'm using Windows 3.1, the whole iPad freezes.
