I submitted content but my Campaign Completion Rate hasn’t changed?

Your CCR won't update instantaneously. There is a cool-down from when you submit your content to when it affects your CCR percentage.

After submitting content to a campaign, there is a 48-hour cooldown period where the developers can review your content to make sure it is relevant and appropriate for the campaign. If your content is not rejected, then you will see the appropriate changes to your Campaign Completion Rate (CCR)!

tl;dr - Wait 48 hours after submitting content to see the number go up!
