There is a workaround to achieve this. All sections of the application must be conditioned. Let's say you wish to distribute your app till November 21, 2021. Then, in the section TODAY"22-11-2021," apply the formula in the display condition. Create a new section with the words "The link has expired" by using an HTML block. Use this formula in the display section TODAY>"21-11-2021" .
