Hi there,

Thank you for reaching out to us.

There is currently a bug with WebView being garbage-collected while it is still displaying an ad. This has already been fixed by the Engineering team; however, there is yet to be an update on the release date for the fix. You may follow our blog and our Release Notes for future updates.

In the meantime, you may try this following workaround if you are using the new Rewarded Ad API: kindly retain a reference to the old rewarded ad object, and use a new variable when requesting for a new rewarded ad.

Regards,
Ziv Yves Sanchez
Mobile Ads SDK Team

Hello, is this issue fixed in plugin version 3.18 or we have to wait for the next version?

[Mobile Ads SDK Forum Advisor Prod]

Hi Sailendu,

Thank you for reaching out to us.

I'm afraid the issue may still be present in v3.18 of the Android AdMob SDK, since this version had focused more on the AndroidX migration. In the meantime, you may follow our blog and our Release Notes for future updates.

[Sailendu Behera]

Hello, you said on June 21 that the issue has been fixed by engineering team, and it's been 10 days, so please release the update as this bug is really affecting our app's crash rate. Please...

Hello,

The latest version 3.18 crashes on google login.(GPGS)
