How to know if Hub is offline

How do you know and find out through the app that the hub is online or offline. The app looks normal but nothing is working, so I am guessing the hub is offline. Gonna reset the hub right now and at least see if I can fix it.

If it’s offline, you’ll get a red message right at the top of the app.

I always get a iOS notification when my hub goes offline.

I haven’t been getting these for some time. I used to get them. I reported it to support and they said it is a known issue.
