Use Notes or the activity/comment area provided on that record. Describe what changed, why, and the next step. Likes show acknowledgement where supported; they are not approval, signature or task completion.
Correct editable fields through the form and verify history. Where notes are retained, add a follow-up correction rather than rewriting history. For a locked/approved record, use the supported return, reopen, renewal or variation procedure. If no valid correction path exists, request support instead of deleting and recreating the record to conceal the change.
If a save times out, reopen or refresh the list to see whether it succeeded before submitting again. Do not repeatedly click an action with financial or workflow effects.
