Is there a way to scroll text when readonly is True

Question

I have this .kv code, it scrolls when read only is false, but when read only is true, it doesn't scroll. Please how can I make it to scroll with read only set as true. Thanks

enter code here <January1Window>:
name: "January1"
scroll:scroll
direction:'tb-lr'
size:(1480, 854)
ScrollView:
    id:scroll
    bar_color:(0, 0, 0, 0.4)
    bar_inactiv_color:(0, 0, 0.7, 0.4)
    bar_margin:2
    bar_width:8
    on_scroll_x:January1.focus = True
    on_scroll_y:January1.focus = True
    TextInput:
        size_hint:(0.8, 0.5)
        id:January1
        text: root.showJanuary1()
        padding:50
        readonly: True
        do_scroll_x:True
        do_scroll_y:True
        pos_hint: {'center_x': 0.4, 'center_y':0.35}
        #background_color: 3,0,0.2, 0.7

I don't see any effect from the value of readonly. However, you need to set the size_hint to None for directions where you want to scroll. For example:

    TextInput:
        size_hint:(0.8, None)
        height: self.minimum_height
