UPDATE: Fixed versions of Drafts are available in the App Store as of Mar. 6. Thanks for your patience!

It appears the latest update to the Evernote app (released Friday 3/1) triggered a change in the behavior of the Evernote login process in Drafts in a way Drafts wasn’t prepared for properly. A permanent fix was submitted to Apple on Friday and should arrive in the App Store in a couple of days.

I recommend you wait for the fix, but in the meantime you can get Drafts linked up to Evernote by doing the following – if you happen to be in a big rush:

  1. Delete the Evernote app from your device.
  2. Double-tap home button to show multitasking tray, tap and hold on Drafts until it jiggles, tap X to force quit Drafts.
  3. Relaunch Drafts and login to Evernote.
  4. Reinstall the Evernote app.

After you have established the link to Evernote, it will work properly with the Evernote app installed.
