Yep, same here.

I can confirm that switching the account to a local administrator account worked for me as well, with a forced backup. I also haven't yet let the scheduled run, though I don't anticipate any issues.

Still, I'll apply the update to the fixed version when available, and change the account back.

Thanks James. Not really a solution, as that's a security risk, but a workaround nonetheless.

Great news! Any ETA?

Thanks for confirming that I'm not crazy! Exact same issue here. I wish I could just revert to the previous version to get my backups running again. I hope they fix this soon.
