I'm rebuilding a Cascade Storymap in Portal from scratch which was originally developed in AGOL. We have quite a bit of text and graphics in the immersive section text boxes. This works well in AGOL, the text box will size itself based on the amount of content. In Portal the the box will not resize and scroll bar appears instead. An internal scroll bar in a cascade Storymap does not work.
Am I missing something here or are there fundamental differences between the Portal and AGOL Storymap builders?
Any assistance would be greatly appreciated
