Every time I click to start to watch an ad the screen turns black and no timer in the top corners. This happens in a several app. And I can’t get the rewards from the ads.

Hey there TheDescores,

While you may need to reach out to the developer of the apps in which you're trying to claim awards, we'd like to help by learning more about what's happening, along with ruling out some possible causes:

1. In which apps does this occur?
2. When did this start?
3. Which steps do you take to get back to the Home Screen on your iPhone, or do you simply quit/open the app that's having the issue?
4. Sometimes unexpected behavior can be resolved with a restart: Restart your iPhone
5. We see you have iOS 16 installed, but the the latest version is iOS 16.4.1. You can verify this within Settings > General > About. In case you needed it, this link shows how to first back up, then Update your iPhone or iPad.
6. We also recommend making sure that all apps are up to date: How to manually update apps on your Apple device

Cheers!
