Just sent a bug report on this but interested to see if anyone else is seeing this bug. After installing iOS 10 GM on my iPhone 6S, I have not been able to download any apps from the app store. When I find an app I want to download I click "Get" or "Buy" then depending on if I am buying or just downloading I click install. I am prompted with the request for Touch ID, as should happen. After entering my fingerprint it appears that the app is about to be downloaded. Then another request for Touch ID comes up but this time instead of having my Apple ID displayed it has been removed. If I enter in my Touch ID this time it just disappears and I right back where I started. Anyone else seeing this?
