Wifi symbol not displaying

I'm having this same exact issue.

I recently had to get a new 6 Plus under warranty due to the camera dying in my original one. Now whenever I boot the device the WiFi symbol will not show, though it is indeed connected to WiFi according to my DHCP server assigning it an IP...and if you look on the phone @ the WiFi settings you can see the same IP address.

Ran a speed-test and it is indeed using the WiFi.

I've put the phone in DFU mode and restored it, thinking maybe it had a bad OS install, but that didn't change anything either.

I guess I can live with it...but it's kind of annoying to have to verify I'm connected before using the device too much due to data consumption...especially when I shouldn't *have* to manually verify.

*UPDATE*

Co-Worker of mine just came into the office and is having the same issue since upgrading to 8.4 this weekend. He has an iPhone 6 (non-Plus).

This occurs for me when the Wifi is turned on an off from the Shortcut Pull up menu from the bottom of the screen. If you turn the wifi on and off from the settings menu it appears to reappear.
