"Get help now" just responds with:
Thank you for the information. Our records indicate that your system warranty has expired.
And refuses to help. The old app to work the KVM worked fine, Dell replaces it with a broken app and now since my warranty expired doesn't want to do anything to troubleshoot and figure out why its buggy?

DDPM 2.1.1.12
Directly plugging monitor into laptop and skipping the dock, still won't work
No idea where the DDPM logs anything

Do you remember if the last DDPM 2.0 (2.0.3.9 June 2, 2025) functioned correctly?

All the DDPM versions worked poorer from the previous software. The 2.0 versions took a long time before it finally recognized a monitor was connected. (i.e. start up the app and it sees the dock fine but takes awhile to see the monitor)
