Can anyone reproduce this in CDpedia 7.0 beta 300?
When I add a new album with barcode 0602455919939 for The Beatles - Now And Then (CD Single), the search goes through Wikipedia then starts in Amazon US and the add window immediately closes with no result.
When I open add album again, the barcode is still there but the windows closes again within a few seconds.
I am testing this on an M1 MacBook Pro.
I was able to add the album by reverting back to my App Store version of CDpedia.
If I search using 0602455919939 with Discog's I do get a result for the single release.
If I search using All criteria I get the Doghouse result of the album.
If I search just using Discog's using the title then I get a multitude of results.
Remember you can change your search site by clicking on the drop down arrow by the magnifying glass in the search pane. Then when/if it brings up a result you can see other results by clicking on the right facing arrow just above the blue Add button.
Seems like this has been addressed in CDpedia 7.0 beta 306. Only tried it few times but so far so good. Might have to do with the site searches that Conor has been fixing from other threads in the forum.
