Bug SDK (iOS) Version v11, ad banner not displaying when relaunching app

[Alexandre]

Dear AdMob team,

I have found a bug that is present in all of my apps. One of them appear when I updated my app from SDK v10 to SDK v11. I suspect this bug comes from the SDK. The bug does not always occur, but sometimes, when the app has been in the background for 2-3 hours or more and the user relaunches the app (without killing the app), the banner does not show and reappears after a minute on the screen. I find this bug is also present in the official AdMob banner example on GitHub.

I have tested with different internet connections, and it seems that is not the issue. I see the bug even with a good connection. I also tried on different devices and still encounter the issue on all of them. There are no errors in the logcat when the bug occurs.
I use only admob without any mediation and I have see a decrease in diffusion rate since I have this bug.

Can you help me to find where this bug comes from?

Thank you for your help.

Best regards.

Hi,

We need detailed debug information from a device where it's observed in order to actually make any progress in diagnosing this. The only way for us to investigate further is by creating a project where the issue is reproducible. If the issue is non-reproducible, kindly provide the below mentioned details via "Reply to author" option:

• app ID
• ad unit ID
• List of the dependencies included on your project

Once provided, I'll be raising this to a wider team for further checking and to get their insight as well.
