I have a custom App with a custom Tab called "Activities" that is set as the Default Landing Tab for the app. The Content of the custom Tab is a Visualforce page. With the Winter '16 release we are now getting a redirect message, and I can't figure out what needs to be changed to eliminate the message. The redirect message only appears when the user first logs in and the default "Activities" tab is displayed. If the user subsequently navigates to another tab and then back to the "Activities" tab, the message does not reappear.

You will be redirected to https://ourcustomdomain--dev--c.cs25.visual.force.com/apex/Activities?sfdc.tabName=01ri0000000XOoM.
