PPTP Connection Removed in IOS 10 & MAC OSX 10.12 (Sierra)
This announcement is for users of iPad/iPhones already running on, or updating to IOS 10 and Mac users updating, or already running on Mac OSX 10.12.
You will no longer be able to setup/use a PPTP connection going forward as Apple has stopped supporting it. You can however still use the L2TP connection instead which is still available via the auto download for iPad/iPhone & via the Mac OSX setup guide.
