How do you know you the Sonoma update didn't bring many updates on a coding level? Are you helping them?
Do realise that Pioneer DJ does not only need to update Rekordbox but also ALL the hardware that is compatible with Rekordbox and other DJ software that are officially supported. What might work on 2 device might not work on the other 20+.
Pioneer DJ isn't Google or Apple who have 10.000 engineers working on software. Yet they have a team that is dedicated in bringing out compatibility to all software as quickly as possible.
Any frustrations you might have are you own, as Pioneer DJ has given clear information they are working on it.
