Hi Teejay!

Devices:

It is the 4th most frequent crash. About 1% of daily crashes. The other 3 top crashes are also ad related. But I believe they are either a crash on the Unity Ads adapter or Unity Ads SDK since the thread crashing is the unityAds thread.

Hi Jorge,

Thank you for your response.

I'm a colleague of Teejay and will be assisting you on this. Were you able to replicate these crashes on your sample project file? If yes, in addition to what my colleague requested, can you provide us with a sample app project where this crash is happening as well as steps to replicate the crash log? This will help us to check this further. You can send it Reply privately to author option or send it directly to mobileads...@gmail.com. Kindly inform us on this thread if you sent it directly to the email provided.

Hi!

Unfortunately I cannot make a small repro project. It only happens in production with real ads. I've updated mediations and hopefully the crashes will get fixed with those updates.

Hi Jorge,

Thank you for updating us. Kindly share your findings and if the crash subsides after updating your mediation adapters.
