@michaellev-sp, what Ad Review version are you using in your application?

[Mecze]

We are also seeing this ANR on 8.0.1 using Unity.
our Ad Review Version being pulled by Applovin is 5.6.6

[applovinAsh]

@Mecze - this crash is fixed with ad review version 5.6.6. Are you sure that the crashes are coming from that version?
