Kanban view in the mobile app is very sensitive, when you try to move the screen to view the other columns, the records move very easily. I have tried being more delicate and reduce the touch on the screen but most of the time the record will move to another row/column.
Also, there is a lot of "ADD NEW" options showing. the add new option is under each record, takes up a lot of room. Maybe have Add New to the top & bottom of the columns, not to each row/record.
