Can no longer modify track information or artwork in iTunes 12.9.2.5
Since the installation of Mojave on my iMac around a month ago (November 2018), iTunes does not let me modify titles, information or artwork in the tracks or albums that I add to iTunes.
Is there anyone experiencing the same issue, who has found a way to solve a similar one?
This is really really annoying, as all my music runs on iTunes and I've spent years building and updating my library.
Thanks in advance for helping out!
