Indeed. Rebooting rpi didn’t work. After cold boot everything seems to be working.
updating to 0.74.2 fixed the issue for me 
I attempted to update to 0.74.2 as well. It completely crashed my system. Upon reboot, it will not come back up or load to anything. Now I am stuck having to reload my system.
I’m having issues loading the 32-bit ‘recommended’ image. Also, it doesn’t seem to have resin-sample file anymore. Anybody have idea what happened to it? Is it not needed anymore for static IP assignment?
Same issue after update to the supervisor 225: “Unable to load the panel source: /api/hassio/app/entrypoint.js.” and nothing to do through the CLI to reboot o shutdown properly.
I’m going to downgrade at supervisor 224
Funny thing : you can’t downgrade supervisor. It auto-updates itself again.
Any method to stop It?
Why the possibility to downgrade if auto updates?
