Internet Coection Sharing stopped working after Windows 10 Aiversary Update

Since updating to Windows 10 1607 (the "Aiversary Update") my shared WiFi adapter isn't shared any more.

I share the WiFi coection with a Hyper-V switch so that my VMs have Inteet access via the Surface Pro 2's WiFi coection. But since the update, this only works after manually disabling and re-enabling Inteet Coection Sharing. Otherwise the inteet sharing doesn't work even though the option is set in WiFi properties.

An ideas?
