I am trying to do a mass import to update held users in our system per these instructions: https://help.salesforce.com/articleView?id=000268698&type=1
While I can change users to "unsubscribed" (steps 9 & 10), when I try changing to "active" (steps 10 & 11), the users return to the "held" status. Has anyone else come across this issue and found a solution?
I should note, that I export multiple fields: Email Address, Subscriber Key, Status and Promo Key. We have to keep promo key as this is the only way to connect users to particular titles within our business.
