react-spring - tips for effectively addressing TypeScript typechecking challenges

Using react-spring with typescript has presented some challenges, even on the initial test, as evident from the prominent typescript checking issues below.

Could there be a fundamental error in the way I am utilizing it, or is there a relatively painless solution to rectify this issue?

          <Spring
            from={{ number: 0 }}
            to={ { number: num } }
            delay = {delay}
            config = { config.molasses }>
          >
            {props => <div>{props.number.toFixed() }</div>}
          </Spring>

This code snippet results in the following error:

No overload matches this call.
  Overload 1 of 2, '(props: Readonly<SpringProps<{ number: number; }>>): Spring<{ number: number; }>', gave the following error.
    Type '{ children: (string | ((props: { number: number; }) => Element))[]; from: { number: number; }; to: { number: number; }; delay: number; config: SpringConfig; }' is not assignable to type 'Readonly<SpringProps<{ number: number; }>>'.
      Types of property 'children' are incompatible.
        Type '(string | ((props: { number: number; }) => Element))[]' is not assignable to type 'SpringRendererFunc<{ number: number; }>'.
          Type '(string | ((props: { number: number; }) => Element))[]' provides no match for the signature '(params: { number: number; }): ReactNode'.
  Overload 2 of 2, '(props: SpringProps<{ number: number; }>, context?: any): Spring<{ number: number; }>', gave the following error.
    Type '{ children: (string | ((props: { number: number; }) => Element))[]; from: { number: number; }; to: { number: number; }; delay: number; config: SpringConfig; }' is not assignable to type 'Readonly<SpringProps<{ number: number; }>>'.
      Types of property 'children' are incompatible.
        Type '(string | ((props: { number: number; }) => Element))[]' is not assignable to type 'SpringRendererFunc<{ number: number; }>'.

It appears to be potentially related to a typescript and React.Children issue. React Component children typecheck with typescript

Whoops! Looks like there might be an extra ">" in my previous message. TSX!
