A new update was pushed live today to fix the Yahoo! search results counts in the Online Check add-on module (Yahoo! had made another change resulting in DFP being unable to obtain their results count).
If you have the Online Check add-on module installed, when you next run DFP you will be prompted to install updates. Please click ‘yes’ and allow DFP to install the updates for it as this will enable Yahoo! and Bing search results to pull the correct results counts again.
Also, just to let you know, we have some great new features and updates coming very soon, so keep an eye out for them!
