We are facing issue with aem 6.5 (sp3). Inhertiance lock symbol not showing on experience fragments livecopies.
- Check if the livecopy has proper relationship to the master
- Go to crxde and check if "cq:LiveRelationship" mixin is added to the livecopy and cq:LiveSyncConfig node is present at the root and mapped to the correct master
- Lastly, try to create a new livecopy and see if you can reproduce the same issue
