BTW, if you are an iPhone user and have updated to iOS 11... IT SUCKS! A horrible release from Apple as it is extremely buggy. Very thankful that I did not install it on my iPhone 7, but on my iPad Air 2 it is a cluster fuck, even with 11.0.01 released this week. For iOS users I would hold off on updating until iOS 11.1 is released. FYI, Apple released the first 11.1 ‘beta’ yesterday so I would not anticipate it to be released until Thanksgiving, maybe Christmas?
