How to add the allow-downloads flag to the sandbox tag in iframe
SOLVE
Hey, I'm still getting the same error(Download is disallowed. The frame initiating or instantiating the download is sandboxed, but the flag ‘allow-downloads’ is not set) when I try to download the HTML document as PDF using HTML2canvas function.
Version of my Google chrome is (Version 87.0.4280.66 ).
Off the top of my head, I don't know of a way for you to edit a HubSpot CRM card/extension'siframe attributes, but I want to pose your use case to my team.
Can you confirm your app ID? If you have a link to an example record which contains such an iframe action, that would be very helpful as well. Feel free to share these details with me via direct message.
One more point of clarification: What happens when a user attempts to download the files? Does Chrome throw an alert or only a warning or error in the console?
