Thank you for report. We'll have a look at it.
How many crashes like that are there in the app?

[Usipov]

@kanstantsin, over 2000 crashes for the last 90 days. More than 2000 users were affected.

Further investigation revealed similar crashes on other threads of the app. It looks like, the problem is not in yandex mobile ads
Sorry for disturbing
