Gmail can send but not receive - no errors

I’ve set up Gmail no problems. The calendar has synced fine and I can send emails but no emails are being received.

In Gmail Settings  check the following
Labels       Make sure that  “All Mail” is checked SHOW    It is a requirement in version 7
                  and any other label that you want to see.
Make sure your Import ports on emclient account is correct
Menu-tools-accounts       look at import port  for imap      mine are  993
          SSL/TSL on special port (legacy)

That’s done the trick - many thanks for that.
