Since installing AVG, I am getting limited Gmail on my Apple mobile devices, receiving some emails  but not others.  Some of the missing emails were sent from a friend's personal email account.  Other missing emails are from a business sending from a Google domain.  In the business case, I seem to receive the emails that go to general alias mailing list but not individual emails from the same domain. Is this a problem with AVG?  I had the VPN turned on but have since turned it off and rebooted the devices. 

Thanks,
Linda
