iTunes match not matching or uploading music
I am an iTunes match subscriber. My mac OS and iTunes are up to date. I have approx. 16000 songs in my library but most (60%) of my music has not been matched or uploaded.
After reading many discussions on this topic, I turned off iCloud music library from iTunes, signed out of iTunes on all my devices, restarted iTunes on my mac and signed back in, made sure genius was turned on and updated, and turned icloud music library back on. After this procedure, the iTunes activity window says it is waiting for iTunes to deliver iCloud music library and than, for about 2 seconds, says uploading songs. For 30 seconds, the iCloud status column shows songs listed as waiting and then iCloud icon disappears and iCloud status column is empty except for songs already uploaded or listed as matched, uploaded, incompatible etc..
I also tried iTunes >File>Library>Update icloud music library with the same results.
Any suggestions would be appreciated.
