i have iOS 10 PB 4 installed on my iPad mini 2. Tbf it works fine , & the slight lag & slowness is poss due more due to the iPad than the beta itself. I've been perfectly happy with it for the last 2 weeks , but i k ow at some stage today I will want to use my Sky Go app (UK) on it. Unfortunately this is 1 of 3 apps on my iPad that does not work with iOS 10. Now I'm thinking of going back to 9.3.3 today , mainly so I can use the Sky Go app. If I'm honest , in my opinion iOS 10 adds nothing really to my iPad mini 2. There's no increase in speed or functionality (that I'd benefit from) unlike my 6s+ Anyway , if I delete the iOS 10 profile on my iPad & go back to the current version , can I say tomorrow , install the iOS 10 beta again by installing the profile etc. Or is it a case of once you've deleted from a certain device , you can't install that beta again ? Cheers for any advice.
