We currently have a visualforce tab which is the default tab selected upon logging into Salesforce.  With the Winter '16 update in our sandboxes, now I automatically see a redirect notice "you will be redirected to....<URL of tab>".  I have to click "OK" before it'll open.  Can anyone help point me in the right direction of how I might fix this so we can bypass this fun new redirect notice?

We have created a custom field in the User record which is a checkbox to tell us if someone is a people manager or not.  I'd like to automatically add all people managers to a Public Group.  Any tips?  Thanks!
