This issue is currently occurring on both PS and Xbox.
At first, it seemed to be only occurring on the official Japanese and Asian PS servers, but as time passed, it also occurred in Latin, Oceania, Americas, and Xbox.
It’s not just that the region and game mode have changed; various internal settings have also been changed.
I reported it myself, and thanks to many friends, it seems that the developers have been made aware of this issue.
We are currently waiting for a response and improvement from developers.
