I can't change status while not assignee was added? Is this bug?

Hello,

My app setted assignee for statuses, but one status in middle process did not add assignee. In this status, when I change to next status, the system notificate “No privilege to proceed.” . Is this Bug?

my screenshot is below this post.
Can you help me?
Thanks!

Hello Tan,

Are there any permission settings set up in this app?

When a “No privilege” related error pops up, the permission settings are usually the cause.

Best,
Chris

Hello Chris,

in permission setting, I permisse assignee edit but in process management setting I don’t assign anyone in this status. i think that is reason.

Thank you for your support.
