When attempting to bulk upload Google Mobile App placements, you may encounter the following error message (or a variation thereof):
Placement URL format is invalid
This message will appear in the error file (downloadable from the Activity Log) once the job has been processed.
What Causes The Issue?
At this time, the platform does not support management of Google Mobile App placements, resulting in this error message if you attempt to upload these placements.
How To Fix The Issue
We may add support for Google Mobile App placements as part of a future iteration. In the meantime, please use Google Ads to manage your Mobile App placements.
