so I just created admob account today and, set up in project settings, application store --> google play store pasted admob banner ID pasted admob interstitial ID added admob for both banner priority list and interstitials priority list and also setup in menu editor then tested in both android studio run and actual run on mobile device ads never showing.. What can be the reason? is it because I just created admob account?
It can take up to 48 hours to serve live ads depending on which region they are requested from. It's also important to remember that live ads may not show until your game is registered as live in an App Store. Be sure to test with Admob Test IDs to make sure they're working.
You need to make sure you setup your payment details as well. Otherwise there won't be any ads showing at all. Upon doing that it will usually take within the hour before ads start showing
