After updating my app, I'm now getting crashes when the app is brought to the foreground. On initial launch all appears to be fine. But when I background/foreground the app I get this:
Window container should not be nil.
Unfortunately this is only happening on production release and I cannot reproduce the issue in the debug environment.
I updated GoogleMobileAds to the latest version. I think the framework may be responsible. Curious to know if anyone else has experienced this and knows what could possible be the cause.
