This morning, I corrupted a rule during a paste operation so I took a fresh backup to preserve other mods I'd made, restored last night's scheduled backup, exported the slightly older version of the now-corrupted rule then restored the backup I just took. I imported the slightly older version of the rule and, other than losing the few mods I'd made, things are back to normal... with one exception: all of my cloud backups are missing.
I created and uploaded a new Cloud Backup (which claimed success) but even it doesn't show up. I clicked 'Reload now' next to 'Missing cloud backups' but no help. I 'Reloaded entitlements' and then clicked 'Reload now' again, still nothing. It's been 30 mins or so and still no cloud backups are showing up.
Since I have two hubs, the one in question's UUID ends in eaa5.
I've also just determined that Remote Admin no longer works for the affected hub above (it does for my 2nd hub) and, related I suspect, my Dashboard is non-responsive in the iPhone app/cloud links--local links work fine.
I've since got everything working again. I reset the token, regenerated cloud links for the dashboard, reconfigured the iPhone app and gracefully rebooted (power cycled, too, just for good measure) the hub and it's all working again.
