Hi Mainecoon364,
Re: "Accessibility Display Text Size Setting Does Not Change The Text Size Settings"
As you say, not all text displays larger when you make an increase using the slider.
Eg: Some apps may already have custom text-size settings that may need to be changed.
_________
In Chat GP :
With Chat GP open:
You can click on the View button and choose "Make text bigger"
(Repeat if you want it even bigger)
Alternatively, you can use two keys (keyboard shortcut): Press Command and Plus Sign (+)
Repeat if needed.
Apple support provide an article online that may be helpful.
