Hi, I sent you a message . Have you received it? I think there is an error with the object, because Ironsource said that they have tested with a test app and they can see test adds (while I can't do that if I use the object):
"I have checked your account settings, and for test app e5436d**
Everything looks good, as I am able to get and watch ironSource test ads using your appKey and configurations.
Then I believe your issue maybe related to the integration & implementation,
can I suggest you download our Demo App from our Knowledge Center....:"
