On my newest phone, the HTC One A9, running Android Marshmallow, there are no longer any 1x1 widgets for Calendar, Tasks, etc. that can be placed on home screens. On other devices, I have an option for the "Touchdown HD" widget, which then prompts me to choose which feature I want the widget associated with.
I tried going back to Touchdown for Smartphones, but no luck there either.
Is this a Marshmallow issue? Any help would be appreciated.
