Pixel 4 and 4 XL will not be included in the Android Beta 13 QPR1 program.
The FAQ section of the Android Beta site has a new list of eligible devices, which presumably refers to Android 13 QPR1 (Quarterly Platform Release). The Pixel 4 and 4 XL are not included. And there shouldn't be any surprises here. Android 13 QPR1 is due out in December, and support for the devices ends in October.
The Pixel 4 and 4 XL were released in 2019, and 3 years of support was announced back at launch. After October, the devices may receive 1-2 more updates with a few fixes, but still based on Android 13 with the October patch.
Hurry... the end of support is coming.
