iOS. I lock the phone while the app is showing, wait a few minutes, then unlock. I can scroll the "all task" list up and down, but the hamburger three-lines menu is non-responsive... for about 30 seconds and then suddenly it will pop open properly to show the All tasks/Hotlist/... menu options. I think there is some refresh or load that is going on in the background that doesn't affect the ability to scroll the task list... but for some reason keeps me from changing which view of the list I want to look at. Reproduceable.
