Case replies are not displayed in Salesforce Lightning after the migration
There’s an issue in Salesforce Lightning with Case Replies. Often, they are not displayed after the migration process. To fix this issue, you need to do a few simple steps:
1. Switch your desk to Salesforce Classic version.
2. Look through all the cases you migrated to your platform. You will need to enter each case and then return to the whole list.
3. Switch back to Salesforce Lightning.
Now, all the replies to the Cases you’ve looked through should be displayed in all cases.
