Delay in dimming

Hi- I have Lutron dimmer switch (P-PKG1WB) throughout my house. I just installed one in my detached office. I ran Ethernet to the office and have wifi no issues. When I turn on the newly installed switch, the light does not go on. I turn it off and on and finally it turns on after several tries.

Is the switch trying to communicate with the hub (which is a good distance away)?

Can it use the wifi router somehow?

Why would it be delayed it i turn it on at the switch (and not using the app)?

Thanks.

What type of lighting load do you have on the dimmer/switch? Is it compatible? Try an incandescent light to see if that works and you will know.
