If anyone cares, Bing's reporting has been down for days. It is NOT your account only. I feared the worst this weekend. But they are working it. Amazing that a huge corp like this can have billing down for days. I have been in the engineering world for many years, and never have I seen an outage more than a few hours. Heads would roll for that.
Anyway. status.bingads.com/ gives the latest status...
Yes this has been down for awhile
Bing:
We sincerely apologize for the inconvenience, please be advised that we are currently having a known issue wherein our reporting tool on the UI is not working accurately but ad delivery is not affected by this. Our engineering team is already working on resolving this as soon as possible.
As of now we do not have any timeframe on as to when this will be resolved but reassure that I'll send you an update once the issue is resolved.
