Device history incomplete?

I seem to be missing device events in device history for the past few hours. I’m not sure if there is a platform issue or something else. Seems to affect more than one device. Anyone having this issue? I use the history at times to see if automation is triggering or not.

I see that all the time. Some instances of opening the app, it’s there in full. Other instances nothing.

With that said, I can’t access any devices this morning, so there might be a greater platform issue at play.
