If you are not able to enter the game, please make sure to update it to the latest version.
You can check the Idle Miner Tycoon page on the app store and see if an update is available.
We would also suggest accessing the game while being connected to a strong and stable wifi connection.
If you are still not able to get past the loading screen, you can try the following workaround as well:
1.) Restart your device
2.) Close all other apps in the background
3.) Turn on airplane mode
4.) Try to start the game again
Once you manage to enter the game, please make sure to collect Idle Cash in all of your mines, including Event Mines and Mainland Mines.
Otherwise, feel free to reach out to us at community@idleminertycoon.com and send us a screenshot of the loading screen.
