In the original wording of the message about send to area for symbol arts being disabled this was the message the article here said:
Now with the recent update to the game this is now what it says in the patch notes here:
I get that there were issues with symbol arts being sent during streams, but the solution of setting symbol arts to default to off and adding an option to specify the display area would have worked perfectly. What happened? Didn't think it would be important to tell us you gave up on implementing this change, and that you were planning on making send to area chat for symbol arts permanently disabled?
Someone please tell me this is just a translation error, and SEGA didn't just give up and permanently disable send symbol arts to area, but it's probably correct... and this is another thing they neglected to mention about this update beforehand.
