AdMob Interstital Problem

Hi everyone,

I’m working on implementing AdMob interstitial ads in my app and could use a bit of help. I’ve created a test setup and added blocks for the interstitial ad logic. My goal was to show the ad when switching between two tabs in the app — not when clicking a button.

Currently, the ad only appears after clicking a button, which isn’t the user experience I want. I’d prefer the interstitial ad to automatically trigger between tab transitions without needing any user interaction.

I’ve attached a screenshot showing how I’ve arranged the blocks. If anyone is willing to take a look and share some advice or suggest what I might be doing wrong, it would be greatly appreciated!

Thanks in advance!
