Hello. The ‘Only Show Duplicates’ toggle is available for Qobuz playlists (under Qobuz - Playlists and Qobuz - My Qobuz - My Playlists) but seems to have no effect. See two screenshots with toggle set to No and Yes respectively. I wouldn’t think this is expected behaviour?
I wanted to touch base with some good news, which is that our technical team has been able to reproduce this behavior and we’ve opened up a bug report with our developers.
While I can’t say for certain when this bug will be fixed, getting things reproduced in-house is a critical first step, and I will keep this thread up to date as the team passes along feedback and work begins to get this resolved. Thanks again for the report!
