The black screen issue can happen on old devices.
There are 2 solutions for this problem:
1. Please try to play the game on a different device. (A device with a higher Android version, then your current device. For the best experience we recommend Android 8 or higher.)
2. You can also solve this issue also on your current device even if it's an old device. By buying any purchase in the game from the shop, the ads are disabled after the match. This will solve the black ad issues as it is caused by the ad that is not compatible with old devices.
