iTunes Match won't load all new songs in Big Sur

Thanks for the trouble-shooting suggestions. The songs that haven't uploaded have dotted-cloud symbols, which I believe means they're waiting to be uploaded to the cloud. The computer and Music were authorised a long time back, so just for the heck of it I reauthorised it. I'll try again tomorrow (I'm in Australia and it's night-time now) and I'll post again when I do.

The status column shows that all tracks on all three albums have been matched. Even so, the dotted cloud remains on half the tracks on one and all of the tracks on the other two. There's been no change since I re-authorised the computer.

More suggestions?

Thanks again for the suggestion. I'm not sure I understand this one. The items in question are not in iCloud; that's the problem. They are in Music on my MacBook Pro. Even though they haven't been uploaded to iCloud, will I still be able to find them in iCloud's music library? Sorry for my confusion; it probably reveals how much I don't understand.

Would it be easier if I just deleted the albums from my MacBook Pro's Music library and tried importing them again? The original files I purchased and downloaded from Presto Music are still on my external hard-drive.

Thank you again for your patience and understanding.

Today's revision to Apple Music for Mac (version 1.1.4.110) revealed that the songs have all been matched. That much is done.

However, the songs are still greyed out in Music on my iPhone (running iOS 14.5). When I click on one of those, I get the message "This song is not currently available in your country or region." That strikes me as strange, since I though iTunes Match simply brought my music library into the cloud and, if the song didn't match what was in their database, they uploaded the song file itself.

This is a new issue for me and I don't understand it. I've been using iTunes Match for years and have never had this problem. Even after we moved from the US to Australia in 2017, I still have not had this problem. All the songs that are greyed out were purchased from Presto Music (a legal and legitimate paid-download site for classical and jazz music). All of them are albums on record labels based in the US and all are available for download in Australia on Presto Music, so there should be no digital rights problems. I've downloaded a fair amount of music from them since we moved countries, imported that music into iTunes, and never had this problem before. And some of the songs that aren't available are individual movements of a classical concerto or symphony where the other movements are available! So that makes no sense to me either.

Back in the "old" days (before iOS 14), I could turn off iTunes match, reboot my phone, turn it back on and wait for it to repopulate when there was a problem. Now, I'm not sure how to do that, or if it would even work.

Any thoughts? Thanks.
