I am about to release my game on the playstore, but for some reason my videoads stopped working. In fact, they work just fine if I enable the testmode, but as soon as I disable it ads will never load.
I am checking if the unityads has been initialized, and again everything was working just fine. I read on another thread that changing the name of the project might have something to do with it but PLEASE this is ridicioulus. I am about to remove the ads completely and use only admob instead.
Hi,
Can we please kill the urban legend of renaming project? 
There could potentially be a few old (2+ years) projects where updating the project would re-sync the data to delivery servers, if for some reason the data hadn’t been migrated correctly (but should not be the case). But for recent projects no need.
Anyways, if you get test ads, then the integration is working. Most likely you ran out of ads on that device, see also Frequently asked questions
Also please check the device log using “adb logcat -v time UnityAds:V *:S” and see what log messages Ads SDK writes. If any errors in there, please follow up here.
Thanks,
Rasmus
