Some Cubase midi functions not working

Hi,
I'm having trouble getting some of the cubase midi functions to work.
For example, from the template,
Forward, rewind, stop, these all work. But play doesn't work.
I tried to set up a nudge left button, but that didn't work either.
The stream deck app says" midi configuration OK."
And I checked the studio set up, and it matches with the recommended settings.

The Mackie controls have been reliable, though.
There's some commands that aren't available  in Mackie, like nudge, which I would like to use, otherwise I would just use mackie, and forget about generic remote.

Thank you

Hi,

Please enable extended logging, restart the Stream deck software (important), press the Play and Nudge buttons, and send me the log file (all of it).

Thanks.
Can you tell me how to enable extended logging?

Please have a look at the last section on the installation page in the documentation.
