Thanks for testing. This VideoInWidget is an anomaly in the AD110 API and shouldn't be used. When I tried setting ShowWeek false using VideoInWidget and reported that it worked - I was mistaken. I had referred to my HomeAssistant live view and did NOT see the weekday, but it was obscured by other text that HA has in the upper right corner. I should have used the SH app to confirm.
So here is what I saw in the upper right of the AD110 view in HA - No Weekday! Ha, lol.
