As confirmed through Twitter, your solution to all problems in iOS 10.1.1 is to add support for iOS 10.2, but that yes, not everything is good news.
My fix for the issues in the 10.1 jailbreak will be to add support to 10.2. It will however not work on iPhone 7 on 10.2, just 10 and 10.1.

Basically, the jailbreak of IOS 10.2 is not compatible with the iPhone 7 so users should not update it in any way.
Also, if you have a previous device, my recommendation is to update iOS 10.2 as soon as possible, especially considering that Apple can launch iOS 10.2.1 at any time.
