Problem displaying AdMob ads

Please help. AdMob ads are running and displayed the first time the user enters the application after downloading it from Google Play. When the user enters the application for the second time, the ads are not displayed.

show your blocks ( you must reload after admod showing the first time)

This means that if I close the application and open it again, the ads will appear, but despite that, they do not appear. Please respond.

ex, if you have 2 buttons
when button1 click : call admob banner / inter load ads
when button2 click : call admob banner / inter show ads

Uploading: Scan.aia…

can’t download your file

Can I send it to your Telegram because the download fails every time?
