I've just installed IOS 11 on my iPad Air and it's totally unusable - To start off with, it really slow to boot, moving icons around on the home screen is totally a no go - the screen just seems to freeze up when you try to move icons around the screen. Flicking through the screens on the iPad is just so slow. I had it on my device for about 5 minutes and have now removed it. I understand that this is a very early beta but has anyone else experienced the same issues on an iPad Air? Thanks in advance.
