iPad 2 (Air) extremely slow after ios 11.4.1 update

My iPad Air 2 is pretty snappy with the latest version of iOS. You might do a backup, then try erasing everything and starting over. Maybe something got corrupted and a fresh start might help. If you restore your iPad, instead of starting from scratch ... and it’s still running slow ... then you might erase it again and see how it runs with starting from scratch and using the normal Apple apps. If it runs good then ... start adding your apps back on, one by one and see how it goes. Your iPad Air 2 should run really good on the latest iOS.
