SmartThings Wifi showing hubs as disconnected, yet all devices work

As title says, hub shows as disconnected in SmartThings app. Plume app showing ‘Internet connection lost’ (verified on two different devices). However the network is still up and all devices still work. Anyone else having this issue?

Now it opens up and shows connected but shows the MAC address of all connected devices as well as ‘Online for 18544 days’ for all devices.
