I realise the post title was different.. this is the green dot issue of tracks not uploading and therefor not available on my other Mac or iPhone. I am unable to select all tracks without the green dot and try again. So I suppose that my tracks even though I see them in the list are not actually there at all.. if they do not play.. which is about 80% of my library then they are not actually there? is that the case?
without deleting the entire library and starting again (not the fist time as you know) how can I get my unuploaded tracks up and playable by batch and not selecting each one?
Perhaps you can make an 'show tracks not uploaded' so I can try you batch upload them?
