I have 3 devices, a 7 Plus, an SE, and a 9.7" Pro. The iPhones are both running 10.3.3 beta 6, and the iPad has 11 PB2. The 7 Plus previously also had 11 PB2. Previously, regardless of which iPhone I had my SIM in, the other & the iPad would be able to initiate the Instant Hotspot connection. Now, neither phone shows up in the others' wifi under Personal Hotspot. I have to manually turn the hotspot on, and the connection appears in the normal list of available networks. I've toggled wifi and bluetooth, restarted both phones, manually connected and then disabled personal hotspot. My account does have tethering enabled. Any ideas? Please and thanks.
