Questions to share with IOS

Hi,

I tested some possibilities to use share with my iPhone/iPad.

It is easily possible to send a canvas to the share block and the use this image on the IOS device to print it, to save it to files in iCloud an many more apps. Also possible to send the content of a TextInput field to save the text in file in iCloud.

But:
It is not possible to send the text to the device for printing. Why not?

And there seems not to be a possibility to load a text or image via share block.

Did someone find a way to print text and to load text or image into a thunkable app?
