This was discussed in another thread, where some folks claim that hotspot login still works after the update while others say it doesn't. Since B&N didn't weigh in on that thread, it's hard to know the status of this issue.
In the meantime, the restricted-function browser actually still exists in 1.1.0. This thread has the new workaround to access it. Possibly that might work for you when you encounter such hotspots. You could explicitly open the browser using that method. Presumably you would automatically get redirected to the login screen.
I'll give it a shot. Logging in at work at any part of the hotel franchises I work at is a bit impossible right now (WiFi Login screen I get doesn't ever get anywhere past a blank screen).
If this works, then the attempt to access my Google account should result in an automatic redirect to the Ethostream Accept/Decline page and let me log in without having to also carry my NTablet to work with me just to get my new purchases. I'll try it tomorrow. Thanks!
