Hey guys,
I'm pretty new to FB Ads and can't seem to figure out why I keep getting errors when trying to submit an ad. I've tried with both the regular and power editor but neither works. Both the Campaign and Ad Sets levels say "This item couldn't be uploaded" and the Ads level says
"Unexpected error occurred while servicing async request: An unexpected error occurred while servicing async request. Please try again. (#1487470)"
Any idea what causes this? I've only run 1 campaign so far and then I changed my account to a business manager. This would be the first ad I'm running under that- would that matter at all?
Thanks...

I assume you have tried with a different ad image?
Yes, several different ones.
Yeah this keeps happening to me too.
It happened to me a couple weeks ago and then started working again, and now it's doing it again on a new offer.
Really frustrating.
FYI - I got around this by cloning an approved campaign and then just changing all the details rather than starting a new campaign from scratch.
