If you have an error while connecting your Bing Ads account to the app, it's most likely a permission issue. Before troubleshooting, you'll need to first verify that your Bing Ads account already has data on it so that Polar can pull insights into the app.
If you get the following error, the email you signed into Polar with and the email you set up in Bing do not match.
In Polar, invite the email used in Bing to your Polar account and give that email an admin role in Polar.
Then sign into Polar using this email with which you’ll be able to connect Bing Ads
