I suddenly am unable to edit "Related to" field within Tasks. I added the wrong person and now I can't remove them. This means I have to delete the task and start over? Inconvenient.

YES!!
This is so frustrating.
Really needs to be editable.
What if the “related to” is a person within an organisation and they move on, I need to update this with their replacement.
