I have the same problem as a lot people on this forum. I used the expo Admob lib to implement AdMob banners and interstitial Ads on my App. When running through expo cli on my emulator it works perfectly. When I use real adUnitID it show a real ad. However, after buildling the apk and installing on real devices, the Ads are not showing anymore.
adReceived(arg) - it’s just a logger, which save results, do I have success request to Google ad server or not.
On real device I have err messages. So, it looks like then app doesn’t have permission to making request to the internet.
I don’t have paremission section in my app.json, and any other specific setting in this file. According to Configuration with app.json page - To use ALL permissions supported by Expo, do not specify the "permissions" key.
I found on this forum a lot of relevant topics, for example: first, second, and I have three more.
And no one provided any solution.
If I should provide some additional information, please specify what I need to add.
If there is a solution to this, which I didn’t find then please add the link/
