How did you get on @djbob4321
I saw your PM, looks strange that you don’t have the icon to toggle between the play modes. It’s as if you don’t have the DVS kit activated.
Check your Serato account in the software to see if you are activated for the DVS.
I have never had to use a Serato supported mixer/Controller that requires DVS kit. On my Denon MC6000 MK2 and Roland DJ 808 (both are DVS upgradeable) i didnt buy a DVS kit for them and when i dj at venues that have Pioneers Nexus mixer i only use HID mode (so they are INT)
My own mixers (Rand 62 and Pioneer S9) both support DVS from factory.
Also check the plug in tab in the preferences, where you normally will see Pitch n Time, Serato Video options. You might need to “check on” DVS option there.
