I saw PAYMENT_SYSTEM_OFF in Killbill lib on php.
https://snipboard.io/E0Y58N.jpgBut I can't reproduce it.
I tried reproduce it when setup tags in KAUI
https://snipboard.io/b1lw3f.jpg and rewind time forward, but this state didn't appear.
And I can't find any explain about this state in docs:
https://snipboard.io/YdSl35.jpgCould you explain how can I meet this status in production to decide what to do with it.
I guess this state is not finish and I should wait for someone of: SUCCESS, PAYMENT_FAILURE, PLUGIN_FAILURE
