If you signed up as an advertiser and switched to Influencer mode, the creator side of the product stayed shut: no campaigns to apply to, no advertisers, no applications, and pages that simply looked empty. Switching modes now switches what you can do.
Work as a creator from an advertiser account
Switch to Influencer mode, add a channel, and everything a creator has opens up: campaigns open to creators, the Advertisers tab, applying, your applications, your deliverables and earnings, and interest from brands.
The same goes for Vendor mode once you have a vendor profile. Accounts that signed up as creators or vendors work exactly as before.
One step left? We say so
If you switch to a mode you haven't set up yet, you no longer land on an empty page. You see what's missing and a button to fix it: Add your first channel in Influencer mode, or Set up your vendor profile in Vendor mode.
