ADMOB Extension - callback not firing

The admob extension (Defold AdMob extension API documentation) is not firing the admob_callback event for rewarded ad, i’m a bit confused… i can see the events for the initialization, but nothing for the event reward, i even tried to set the callback again before calling the rewarded ad

i do see the ad, but when the ads finishes and i click the x to come back, nothing happens in the callback

Platform: android
Environment: test ads

i have solved it.

for who comes accross this issue.

if you are using a global lua module to handle ads, you need to reset the callback BEFORE loading the ads if you are switching screens.
