Sync last 6 months chat with whatsapp coexistence

REQUEST_SUMMARY_V2 Problem - Good news! You can now use both WhatsApp Business App and Spur simultaneously. Meta now also gives a functionality to sync last 6 months of chat, which is currently not supported in Spur. We are figuring out how to bring this, do upvote this feature request if you want it to be live sooner, currently there is no expected timeline for this as it has no upvotes Expected behavior - Support this behavior in shared inbox without manual workaround - Maintain clear ownership and state transitions for conversations - Keep agent actions auditable in activity logs Business impact - Reduces manual operational effort for teams - Improves consistency and customer experience - Helps teams move faster with fewer support escalations Legacy category: New Feature
