Stuck on Syncing Your Library on iPhone

I recently signed up for an Apple Music trial. I enabled library syncing on my MacBook but on iPhone I’m stuck with the message “Syncing Your Library” with the progress bar getting all the way to the middle, and after a long while it just cancels itself. I’ve tried uninstalling and reinstalling the Music app, logging out of my account, restarting the iPhone, disabling and enabling library syncing on my MacBook, disabling and enabling library syncing on my iPhone, but nothing is working and no music is showing on my iPhone library. If I go to music.apple.com on the browser I can see my music is already there, as well as on my Apple TV, so it’s just the iPhone that isn’t working. What else that I haven’t tried could I do?
