Why are ads not working after publish?

This is a weird bug that i havent specifically found around here.

The ads do work if i install the shipping apk from my phone, if i install from the play store the ads dont load.

This happens to both ads, interstitial and banners.
Any suggestions as to why that may be?

It is my first app so i dont know if i missed something but test ads worked fine as well.

Thanks in advance for any insight!

Hi. Which plugin did you use for ads?
