question

Hi Steventon, Thank you for bring this into our notice. One thing, I did not find the error in the crash logs reported in your app in distribution portal. Can you share the app name so that I can send to internal appropriate team. Also how and where did you get the crash reported.

Hi Steventon, 1. What version of the MobileAds SDK was used in the App when this issue occurred ? 2. Did this issue occur only once ? or Does the issue reproduce more frequently or consistently ?

Sorry, I don't check this forum very often. Occurred in the latest SDK. v5.1.153. App is [WordHero]. Package is com.rhs.wordhero.

Thanks, did this issue occur only once ? or Does the issue reproduce more frequently or consistently ?

Also, I just looked on all the crashes reported in to our system, I did not find the one you have mentioned. Are you using any other tool? Please let us know how frequent the crash happens in your app due to same reason.

Please reply.

I have not seen this very often. Maybe 1 per week with 50k DAU. The crash was captured with Crashlytics.

Thanks for the reply. Passed to appropriate team. For other developers, below crashes are being detected from Mobile Ads SDK. We are working on these.

Crashes #2 and #3 are fixed and targeted to be released in the next SDK update. Crash #1 is already fixed in SDK 5.1.242 (the current version on the Developer Portal).
