Warning: if you have a lot of safari tabs open or just a few that you’ve been meaning to go back to on the iPad. DON’T DO A RESET AND RESTORE. You’ll loose them all. It seems there is a bug with restoring safari state and new windows. I lost all 50 tabs I had open. Restoring from a older back up didn’t work.
This happened to my brother a couple weeks ago on iPados13.3. No beta. Opened up Safari and it closed all of his opened tabs he had for months.
