I'm having a lot of difficulty opening Accordance and swiping from the bottom to access the Dock to drag a second App onto it. It takes up to ten swipes or more to access the Dock, and I can't tell why it works when it does. Then, when I tap back into Acc and swipe from the right to access the App, the same thing happens. What I get almost every time when I swipe from the bottom or side is something that looks like a flattened arrow head, instead of the Dock on the bottom or my App on the right.
The opposite is not true. If I open an App first, and then drag Accordance onto it, it works perfectly.
I've also tried the "different methods to add apps" at https://www.cultofma...it-view-ios-11/. Nothing seems to work easily or consistently if I open Accordance first.
I have an iPad mini 2, Model A1489.
