Me too. But my Dish Anywhere issues got much worse (e.g. unable to even log in and see the guide when using Firefox on a Mac) after the U511 update to the Hopper 3 and the Hopper 3 “U511 look” updates to Dish Anywhere (e.g. the red underlines in the guide. etc.). Apparently the Dish software engineers/ managers haven’t learned that updating too many things at the same time is a recipe for issues that are harder to find/fix....I've had issues with the web Dish Anywhere long before U511 was released.
FWIW I can log in to DA again using Safari AND Firefox. Wonder how long it will last this time ;(
Edit: And the answer is — less time than it took to type the above post. I can still log in to DA with both Safari and Firefox, but neither one will display my recordings or Prime Time Anytime -- again
