Please look into it.

Hi @maxakash when do you encounter this error? E.g., does this happen when you start the app ? Does this happen with a specific ad format; when you try to load or show an ad??

I understand you're getting an error when trying to use Vungle. Could you tell me more based on the questions above ?

The exception being mentioned in the issue is a handled exception within Vungle's SDK, and should not result in any anomaly or loss of functionality. They will improve this in our future release to hide this, as otherwise like in this case it might create some false alarms.

If you are still facing the issue, please send stack traces, as the stack traces above all have Vungle's SDK in it.
