I have three devices, each with different operating systems. I use – an Amazon Kindle Fire running Google’s Android 6.3.1; a Windows 7, service pack 1, pc using Google’s Chrome 20.0.1132.57; Apple iPhone using OS 4.3.5.
I too was always getting logged out if I used the navigation links at the top or bottom of the home page or went directly to the forum with a shortcut. I found that if I always started at the MIF home page and used the graphic box in the lower left corner “Need Support? Click here to reach out on out online forums.” my previous logon would be recognized and I would not get logged out.
This post will be from the Windows PC using Chrome and if successful, I’ll try from the other two. Hope this will help.
