Ads showing up in editor, but not on device

When I click the watch ads button to double my gains when I die, it works on the editor, but when I export the apk to test the ads, it doesn’t work. I already made a new project and paste the files all the same and yes I have wifi in the device. Does someone else has this problem and fixed it??

I too have the same problem! Have you found a fix?? @Talion1999
