Hi David,
Thank you for providing to me the affected Ad Unit IDs, as well as additional insights about the issue.
The code snippet you provided seems to be very straightforward so I would not expect it to cause any issues. I also tried the affected Ad Unit Ids on my end using
our sample apps and I was able to receive ads from all of them. I would like to point out that the error you are receiving may simply indicate that there are no ads to be displayed at the time the Ad Request was sent. This can be classified as intended behavior since the SDK does not have any control over the available ad inventory. One way to help lessen the occurrence of this error is to implement
Mediation in your application to help maximize fill rate.
However, for us to further investigate, would you be able to provide to us
