Posts on Google For Verified Knowledge Panels Are Going Away
https://searchengineland.comOn July 20, 2021, Google will discontinue the ability for those with verified knowledge panels to use Google Posts. To be clear, this only impacts verified knowledge panels, not the local Google Posts you manage within Google My Business.
Starting on July 20, 2021, you will no longer be able to create new posts via Posts on Google or use the authoring tool to make updates to the knowledge panel.
