Little update re secondary issue (ads not availiable): Not heard back from IronSource yet. I tested on iOS with a similar setup and similar result.
I’ve now tried switching to manual loading of rewarded ads just out of curiosity, and when I manually load I get a different error message: Error ironSourceSDK API: No rewarded video configurations found
And the onAdLoadFailedEvent event fired with the following error info:
508 : Rewarded Video - the server response does not contain rewarded video data
Getting the same error after adding non-bidding ad units so that wasn’t the issue. I’ve found another thread here in which multiple users complain of a similar issue, so it sounds like it might be a problem with the account approval process or something.
