i have the original iPad Air that was updated to 10.3.3 on accident (4 year old son pushed it and I was too late to cancel) back in 2016/17. I did not do a clean update and Safari is running slow no matter what. I read a lot of mixed reviews of iOS 11, but iOS 11.3 looks promising. Should I update with a clean sweep of my iPad in hopes safari runs smoother or just stick with 10.3.3? If 10.3.3 was still available I would do a clean restore of it, but it isn't.
