Re: Changed functionality from 14.3 to 15.3

We are experiencing different functionality once we upgraded from Postgres 14.3 to Postgres 15.3.
Below is a test case that we created which shows a schema user who has a VIEW that accesses a table in another schema. In 14.3 the schema user is able to create the VIEW against the other schema's table and successfully SELECT data from that VIEW as well as directly from the other schema's table.
In 15.3 the same setup does allow for the VIEW to be created however, the schema user is unable to SELECT data using the VIEW or directly from the user's table.
Is anyone aware of changes that would cause this functionality to stop working?
