Apologies if there have been questions like this before. The only solutions that I have found are for document library and not SharePoint list I am just really stuck on this problem within my powerapp.
I have an app for a medical clinic where the user fills out a form and signs it at the end with a pen input. The information is then submitted into a SharePoint list (not document library).
So far, I have managed to get the pen input to save an image file in a document library, but I then need this reference in the SharePoint list and i also got the base 64 code of the image in the list but when i'm trying to decode that code it gives me a blank image.
I tried to create a flow that attaches the image to the last item created in the list but i can't really get that to work.

You can try steps from Matt's blog post where in he explained the steps on how to save the pen input to SharePoint list.
