Apex Legends - "Voice and text chat aren't available for your account" on PS5

I'm reporting what appears to be a bug affecting communication features in Apex Legends on PS5.

Whenever I hold the touchpad button to open the chat in a match, Apex Legends displays the message:

"Voice and text chat aren't available for your account."

I cannot use voice chat. I cannot hear other players. I cannot use text chat.

In Settings -> Audio, there's only 3 options: "Master Volume",  "Audio Mix" and "Advanced Audio Options...". Below these settings the message is being displayed again. 

I have already verified the following:

I am over 18 years old (26).

My EA Account date of birth is correct.

My email is verified.

My account has no sanctions or restrictions.

My PS5 has no parental controls enabled.

My EA account is linked only to my PlayStation Network account and Twitch.

My PlayStation account is an adult account.

Apex language was tested in Portuguese, English and Japanese, with the same result.

The voice chat is ENABLED in the in-game settings.

I also performed additional troubleshooting:

I logged into Apex using a different PlayStation account on the same PS5. The exact same message appears.

I tested another EA game (Battlefield 6) on the same console, and voice chat works normally there.

Additionally, I always played with two friends of mine. One is Brazilian and the other is American. I'm also Brazilian. My Brazilian friend is facing the same problem, but the American one is not having this problem.

Could you please investigate and solve this for me? 

Thank you.
