Well, this gets more confusing by the day. I had cleared the duplicates problem by deleting the database and starting again, letting AS import a good (duplicate free) V3.5 database, all seemed OK, other than AS was doing its ‘analysing’ thing again, but we all understand what’s is going on there now.
This morning I start up AS to see it spending a while ‘synchronising’ - the upshot is that I now have many albums with duplicates again. I have just checked through a random selection of albums and quite a lot have duplicates.
Strangely, nothing has changed in my local music library, I haven’t fiddled at all, no new album covers, no new albums, nothing.
When you just want to play some music the question has to be asked - do I really need to waste time with this?
My AS trial ends today (I have requested an extension) but I think it is time to just give up and go back to V3.5, perhaps revisit AS sometime in the future.
