Could you also please let us know if, during the creation of the single keyword campaign, did you get any other notification with an error? Or they didn't appear in your account after launching? Manual syncing may help to sync data correctly (you can find that step here). After you have performed this step please contact us at firstname.lastname@example.org and be sure to lets us know:
1) Your account name, marketplace, campaign, and keyword
2) A picture is worth a thousand words, they say! If you can capture the issue on your screen and attach it to your response, it'll be like shining a light on the dark corners of the app's jungle. This will give us a visual cue and help us analyze the situation more effectively.
4) We want to avoid retracing our steps, so let us know if you've already tried any tricks or workarounds. This will help us focus our efforts on new solutions.
Once we have this information we can send it over to our tech team and they can get to work correcting the issue.
We look forward to speaking to you soon!
