Patch release.
Yes, recently the app has been freezing after receiving a rewarded ad. On the forum, the developer said they were aware of the issue and would fix it in the beta. The beta was released, followed by a new official release. In the new release, I checked and it still doesn’t work, while the beta strangely fails to load half the project, making parts of it invisible. That’s about it.
Best of luck to you with your endeavors and to a patch getting released soon.
