Nope It works fine for me-- I just checked. But I did have same problem with MB this morning.. It seems that sometimes the saved "favorites: short cuts" get corrupted sometimes and need to be reloaded.
Do a search for
SM website on Google or whatever and re save it in favorites tab-- if this works delete old short cut in favorites.
Or did you "forget to pay your bill" If you have a credit card saved w them and the card has be comprised they may not be able to auto collect n need new CC info.?
Hope this helps.
