Instant Hotspot / Personal Hotspot Not Functioning Correctly
Repost due to header spelling fail... Sorry!
Performed the iOS update to 8.1 and the instant hotspot isn't functioning. Whenever I try to connect from my MacBook I get the error: Failed to enable Personal Hotspot on "Tim's iPhone" - Check to see if the tethering device is turned on and in range of your computer.
I've reset the network settings on the iPhone, cleared all of my saved networks on my MacBook to try to get it back to a semi-reset state (though I did a full drive erase and installed Yosemite from scratch so I can't imagine my settings are very far from virgin state yet) but I'm still unable to connect unless I manually turn on the Personal Hotspot on the iPhone first (even then, connecting is a bit hit and miss which was never a problem before). Restarting each device multiple times and logging into and out of the iCloud account on each device hasn't changed anything.
Even worse is that, prior to upgrading from 8.0.2, the feature worked perfectly between my iPad and my iPhone. It even shut the personal hotspot off as soon as you disconnected from the iPhone. Now, it's hit and miss as well; Connecting every 3rd or 4th try but leaving Personal Hotspot "on" on my iPhone after disconnection.
The smooth experience between my iPad and iPhone is what gave me such high expectations for the Yosemite release. Now I'm sitting here with that still not functioning and the original experience gone. How disappointing.
