I am still having an issue with the app using mobile data when the app is off AND set to only run on WiFi. I think this might be an issue with the ads.

Regarding the issue, when the screen is off or the app is in the background there cannot be any ad requests.

If you still have ads in the free app it looks like the Donate app isn't installed on your device anymore. Open the Play Store app and make sure to install Podcast Addict Donate.
