I use GOOGLE AD MOB on my IOS and Android.
At first, I used the official test ads ID of GOOGLE AD MOB and everything worked normally until I started using the test device.
According to the official requirements, I added my designated devices Android and iOS in GOOGLE AD MOB, and changed the test ID ca-app-pub-3940256099942544/1712485313 to the ID generated by the advertising unit like ca-app-pub-xxxxxxxxxxxxxxxx/xxxxxxxxx , I can’t open the ad normally, and I get the error " A call to load an ad has failed due to an internal SDK error".
Why do I get this error?
