No available opponents in Arena Defense?

[Ogami]

When I go to my Arena screen, while I have available matches for "Attack", my "Defense" list has been empty for a couple of days now. Any idea how I fix that?

Hello Ogami,

Thank you for reporting this. Can you please let me know if you have actively been fighting other players in the Attack list over the past couple days?

...maybe it just needed some time after the last patch. Thanks for following up
