Android 14 beta test will begin in April 2023. Android 13 QPR will end in March.
Google has updated its FAQ section to indicate that Android 13 QPR beta updates continue through March 2023, after which the Android 14 beta test will begin. This coincides with this year's Android 13 timeline.
Most likely, the company shortened the Android 13 QPR program to avoid confusion when two beta tests were conducted simultaneously, like this year. No, QPR3 is not canceled, just that there will be no public test.
