Unfortunately both iOS 8 and iOS 9 builds will crash if a browser widget 
included - these very old versions of iOS (whilst they have WKWebView) 
seem to like modern uses of it (they also have problems with the 
player implementation!).

We kept the min version to allow as low as 8 as apps not using the 
widget work fine (although I wonder if that actually provides false 
in a way so might have been an error - perhaps we should just remove 
options from the S/B).

It could be that iOS 10 is suffering the same problem - @Jacque can you 
any crash logs you can get to a bug report so we can check? (And indeed 
building and running an app which doesn't include the browser widget on 
old device you have access to?).

If it is confirmed that iOS 10 also has a problem with the new browser
implementation on iOS then there isn't really much we can do there.

Its probably worth mentioning that based on looking at few different 
sites on the matter - devices running iOS 10 and still attempting to run
apps / fetch websites now makes up < 2% of all iOS OS usage and that's
dropping by about 0.3% a month. iOS 9 usage is already < 0.5%, and iOS 8
is almost non-existent.
