After updating my iPhone to iOS 26 beta 5, Apple CarPlay is working normally, but the icons and fonts are very small, as shown in the attached picture.
I will also attach a picture of the Zlink app version, as well as the device version.
The purchase date was October 2021.

@Gaby Mlko I don't know if you've figured it out but with ios26 there is a "Smart Zoo " setting now. Go to settings in CarPlay when your phone is connected to CarPlay then click on the settings icon then click on Display Settings then turn "Smart Zoom" off.
