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.
cheers.
