As promised, keeping thread members updated on this process. The Dynamics Campaign Sync item was turned on but didn't seem to fix what now seems to be a weirdly specific issue.
We have two custom fields called Source Campaign and Source Campaign Most Recent, which is where we add the Campaign ID from Dynamics. When leads are either imported with the Source Campaign field, or updated via Marketo Smart Campaign, the two fields are showing the right information within Marketo; however, that data isn't syncing over to Dynamics, even if the lead itself is syncing (all other new data is matching what I see in Marketo, so that's how I know the person sync is happening).
This is for leads in the new workspace, so not sure if that has anything to do with it but as I upload new lists into our Default workspace, I'll check whether those leads also fail to get that information in Dynamics. The strangest thing is that this hasn't been an issue to date - I only noticed it with the new workspace/partition uploads but, as you know, there aren't specific settings for those and everything is connected to the same Dynamics instance.
Still super baffling but I'm waiting on a reply from Marketo Support (assuming I've sufficiently baffled them too 😋). Will keep updating as I learn more!
