This problem can occur for two reasons, either because your OS (operating system) is out of date or you are trying to access the platform through WeChat.
If you are using WeChat you can download the M4JAM app on your mobile device if you are a Android user, alternatively you can access the platform through a web browser.
Please make sure you have the latest OS version and continue jobbing from www.m4jam.com.
If you're an Android user, follow these instructions:
Menu -> Settings -> About Device.
Check to see if there are any available updates for you and if so, select to update your OS.
If you're on iOS (Apple iPhone) follow these instructions:
Menu -> Settings ->General -> Software updates
