Change the language and market in an existing ad group
Currently, you can't change the language and marketing setting for an existing ad group. You can only set the language and market setting when you create a new ad group
Thanks for the feedback on the need for this capability. We are in the process of adding the capability to specify language at the campaign level and allow it to be modified.

Hi, The fact that Adwords campaigns are uploaded into BAE or Bing Ads, language is often set as English by default. I've had advertisers complaining as their adwords file is well set with the proper language. This issue is, no Ad is running, and if we want to change the language, we have to export and import completely again the file. Note this is time consuming, a bad experience for the customer and we lose history of the account doing this. This is an important feature which could be release easily in BAE. Thanks to take this into consideration.
