Ever since the latest iOS update 13.1.2, whenever I open safari it goes to a blank page with just my favorites listed. All my previous tabs and open websites from my previous use in safari are gone! Previously I would ha e 4-5 tabs open to various sites and when I would close app and open it the next day all the sites were still open, now they are all closed with only one tab open for favorites. How do I go back to the old way? I am a grad student and often do research on my iPad which I leave and go back to several times during the course of se real weeks and this is extremely irritating to lose all that work each time I close the app.
