Since updating to the above I have noticed a marked lag in the opening of various apps on my 2017 iPad. The Verge and Kindle being the most noticeable culprits, I know that this usually happens as a device moves further away from the IOS version it was issued with, but I am disappointed that my iPad gen three is at the moment faster than my gen five ! This is a thing that I am sure Apple will not want to address but it is tiresome.
