This is not unexpected because Sony had planned the ground. The Japanese manufacturer recently officially developed the PS4 of the PS4 section.
A few days ago several players were invited by Sony Interactive Entertainment for the preview of the PlayStation 4 update 8.50. If any new things are in the software logically, it's always a removal. The Japanese business announced that the Communities tab introduced in September 2015 had been deleted via e-mail. And both teams will be affected shortly...
The end of Communities on PS4
In an Email sent by Sony to its customers, the 8.50 device updated that will soon be deployed confirms the absence of PS4 Communities. The role was to unite players around their favorite licences. Then they could post notes, build voice chats and even enter progressive games via parties.
Therefore PS4 will be revealed by the Group function from April 2021. On PlayStation 5 several group features are already included and a portion can therefore not be added on the machine.
