Hey Tarek!! Thanks for flagging this, were the columns removed by chance? Couldn't find them here. Adding Keethu R. for visibility and insight when available. If it would be possible to add a filter for this? :)
Apologies for the delay here - just checked and Lemlist doesn't actually allow us to provide any filters here. There is a separate endpoint to update a lead in a campaign (used in our Update Lead integration) and wondering if that would be a workaround here although I would need to play around with it to test since I'm not 100% that it would work since the error here is that the lead is already in anothercampaign.
Hello Keethu R. thanks for your help on that! I have a campaign, I'll try with the update lead workaround. Thing I find weird is that within Lemlist they have a functionality to copy leads from a campaign to another. I'll also try directly with them. Let me know how your tests go :)
