Todo subject field

Hi All,

My issue is the same issue that everyone complained about but still without a proper answer hopefully this thread would be reach a person who knows.

I am trying to create a field in the Todo to show a subject and make the user who creates it to enter data inside of it, once I do that and a user creates an issue it shows a warning message.

Would appreciate if someone can answer this.

I failed understanding what you want to achieve and what problems you faced when you do the customization yourself.

some step by step screenshot with needed explanations will be helpful.
