This fixed the shortcut issue for me.
At least for now.
Barring the iCloud Drive update.* I signed out of iCloud and back in.* iCloud Drive says "on".* But turned everything off on iCloud, except Contacts, Backup (but turned everything off within the Backup option, as I don't need any of them backed up, and I'd have to pay for more space on iCloud to be able to), and Find My Phone.
Shortcuts came back because of signing out and in, but I'm thinking because I kept Backup "on", my shortcuts haven't disappeared.* It's been almost 2 days, and they are still there.* Before doing these steps, my shortcuts would disappear after only a few*minutes of signing out and in to iCloud.
Except for a wifi glitch that made my shortcuts disappear for a few seconds yesterday, my shortcuts haven't disappeared.
I even turned off Backup just to see what would happen. *But the shortcuts stayed. *I'm guessing because I chose to do an actual Backup on to iCloud. *My shortcuts synced, a remained in sync. *That's just my guess based on the trial and error methods I've done.
But it still points a finger to issues with iOS 8. *As I've never had to do any of these under iOS 7, and never had issues with shortcuts. *Another thing to point out. *Since updating to iOS 8, my generic charging cable I use at work no longer works as it used to when I was using iOS 7. *I get a message saying it's incompatible. *And it either isn't charging, or charging extremely slow. *Prior to iOS 8, that cable charged my 5S pretty quickly, with no issues. *Oh Apple. **shaking head*
Hopefully this will help others.
