Hello Igor,
As mentioned in the previous email, it doesn't look like a Unity plugin issue, but there are tasks that are blocking the thread to show the interstitial ad, so it gets timeout eventually.
From the screenshot you provided previously, you are calling `interstitialAd.show(activity);` within `activity.runOnUiThread`. From
its API description:
"If the current thread is the UI thread, then the action is executed immediately. If the current thread is not the UI thread, the action is posted to the event queue of the UI thread."
Can you follow this
system tracing guide to inspect/capture the thread activity, and make sure nothing is blocking the thread from showing the interstitial ad?
Regards,
Joshua
