All Wyze Sense sensor notifications\ actions are running about 30 minutes behind @WyzeGwendolyn
I experienced delays earlier today too. I noticed because one of my Alexa rules chimes when the front door opens, and it chimed about 10 minutes late. Then friends mentioned they were having delays from sensors.
I just now tested and everything is back to having no delay either through Wyze or Alexa for anything that was delayed earlier. Both actions and notifications are back to normal when I just tested.
For me the delays were closer to 10 minutes. Hopefully fixed now.
