Most devices showing as offline but only in new App

Here we go, the title was almost the same:

All Devices Offline, But Still Function When Tapping (Hub is Online)

JUST getting started with Smartthings, although I’ve spent plenty of time in the past creating pretty complex Stringify flows, etc. I have also already installed WebCoRE and run my first test piston successfully. For some reason though, all my devices are now offline, except for my hub and 1 light. When I click an offline switch though, it still works. In my googling I went into the classic app to turn off Device Health, but that hasn’t changed anything. Any ideas?

@Brad_ST, is there any know issue today with the C2C devices?
