Universal Mobile Ads 2.0 is has a problem with loading ads, until I restart the phone.
Pre-conditions:
- Ad mediation order is Chartboost -> Vungle -> Ad Colony -> Unity Ads (Rewarded videos)
- No frequency caps
Steps to repeat:
- Install the game to Android: Skate & Strike
- Tap shop button and watch an ad. It will work fine.
- Close shop screen, then reopen it. You will see that another ad is successfully loaded.
- Press home screen, then remove the game from the RAM using task manager.
- Launch the game again, and go to the shop.
- You will see that ad is not loading anymore, even if you wait for minutes. It say it is a network error and ad is never being loaded. If there isn’t any problem with loading ad, wait for a couple of hours and try again producing the problem.
- Restart the phone.
- Now it will load an ad successfully.
Same thing is happening with interstitials too.
