Why are my mission symbols or graphics not appearing for other team members?

Symbol sharing issues are commonly caused by:
• Insufficient permissions for the symbol type
• Filtering settings on recipient devices
• Network data filtering
• Classification mismatch
• COT message formatting errors
• Symbol placed outside geographic boundaries
• Server-side filtering rules
Check that both sender and recipient are in the same mission group with appropriate permissions. Verify that recipients don't have symbol filtering enabled.
