Automatic Send and Receive

I have the latest version of eM Client and must manually use the Send and Receive button to receive emails. The Help for eM Client says that the interval between Send and Receive automatic requests is settable in “Tools - Settings - General - Send and Receive”. When I look at the setting menu under General there is no link to Send and Receive. What am I doing wrong?

Tools - Settings - General - General and “Synchronization box” there are two options. You are looking for “Synchronize items every … minutes”
