I found this odd that some of my Bing Queries will not refresh today.
The strange thing is......1) Some bing queries work fine while others fail 2) Some clients work 100% fine while others fail
Normally these errors aren't this random and/or give me some sort of explanation but you can see here is basically says try back later.
this is most likely caused by a temporary glitch in Bing Ads API. Please let us know if you keep experiencing this issue.
