This afternoon I turned on my iPad and my Safari browser area at the top of the screen was black with white letters in the address and tabs area. Before it was the opposite with white background and black letters. I usually keep tabs for USAirNet weather, AOPA forum and POA forum. My tabs were all gone. When I created new tabs and went back to the AOPA and POA sites, I was logged out of both forums even though I have the "stay logged in" box checked on both forums. I logged into POA again and looked at the new posts. I closed Safari down and came back after supper to look at POA. Again it was logged out. I checked my Safari settings to ensure it was allowing cookies and it is. I have not run any updates on my iPad. It was not this way this morning before lunch. This is so frustrating having to log in every time I come back to a forum. Does Apple just change stuff on your iPad or install updates behind your back without your concurrance? Anybody else experiencing this?
