I've been having an issue that seems to happen about once every day or two. When using the Smart Keyboard to close a tab (keyboard shortcut <command>+W), suddenly all the tabs that I have open close and I am left with a blank screen with only the address bar. At that point, I can type in a web address, but it won't load and Safari seems to be stuck. If I leave Safari, force close it, and then go back in, all is fine. This has happened numerous times, and only seems to happen when I have many tabs open (more than 5). Has anyone else experienced this? I'm thinking it may be some sort of issue with the latest iOS update. I only had the Smart Keyboard for about a week before the latest update, but never experienced this issue until after the update.
