Icons not showing on iPad 2

I upgraded from 2021.10.7 to 2021.11.1 and the MDI icons no longer are displaying in an older version of the app on iOS 9.3.5. I was happy to see that the widgets were fixed a few releases ago and helped extend the life of this device. Would this be more of a frontend issue?

Same thing here.
Was working fine on 2021.10 and no icon on 2021.11

i had to stop using icons in my picture element that i use as a floormap of my house.

using images worked

so i whent from
- type: state-icon
entity: switch.chambre_aimee_lumiere_noel
tap_action:
action: toggle
style:
top: 87%
left: 80%
color: black

to
- type: image
entity: switch.chambre_aimee_lumiere_noel
tap_action:
action: toggle
image: /local/light_on.png
state_image:
‘off’: /local/light_off.png
style:
top: 30%
left: 50%
color: black
