We apologize for the extended period without updates regarding this issue.
We're still seeing Instagram's "Say hi to new followers" (Follow to DM) automation trigger inconsistently or not at all for some accounts, even when it's set up correctly and the account is eligible.
The cause is on Meta's side. We've reported this to Meta and are in ongoing contact with them. Meta hasn't shared a timeline for a resolution yet.
Other Instagram triggers are not affected. These include Comment to DM, Story Reply, keyword and DM triggers. You can keep using them to start conversations with your audience.
We'll keep this incident open and post an update here as soon as Meta shares new information.
