We’re told in the documentation that you cannot have multiple frame orientations in a single prototype. We’re left with just that! No explanation as to why this limitations was maintained.
I can think of many reasons why one might want this, but it comes simply down to the fact that prototypes probably encompass a flow, and the flow you’re designing may support or even forcibly impose orientation on the user. In this case, you’d want to switch between the orientations in the prototype.
Is there a strong reason why this was not supported?
