Topic: my ps4 wont activate as primary console

"I'm encountering an issue with my PS4 where it won't activate as the primary console. Despite trying to activate it with multiple accounts, including creating a new one, the problem persists. I've even updated the firmware, but I keep receiving error code CE-40947-4. It's worth noting that my account works perfectly as a primary on other devices. Unfortunately, the solutions I've found online haven't worked. Any suggestions or advice would be greatly appreciated. Thank you!"
