Garageband created music no longer plays on my iPhone after downloading Mac OS 27 GoldenGate (27.0.1)

I have a MacAir and recently downloaded the new Mac OS 27 GoldenGate (27.0.1). A few days later I synced my Music in my Mac with my iPhone (SE 3rd generation) and now all the music I created in GarageBand that was on my iPhone will not play. I have read there have been problems with GoldenGate and Music but I can't find any solution that seems to work other than waiting for a new version of Mac OS 27 to be available. What can I do to restore my GarageBand created music on my I-phone?
