With the recent increase in the iTunes Match limit, I happily have uploaded all 60,000 tracks that are in my iTunes library. iTunes on my various macs are having no issues, but the Music app (on my iPhone and iPads) seems to be struggling. Regularly it stops updating with latest changes. Changes show up fine in iTunes on my Macs, so it's not a service issue. My fix is to turn it off in the iOS settings, then turn it back on. And then it works for a while, but then eventually gets 'stuck' again, no longer showing updates. Anyone else have a large iTunes Match library and having similar iOS issues? For added info, I do *not* use Apple Music. Only iTunes Match.
