Thanks a lot! Looks back to normal: perfect
Nope, my cards are not working (and not validating) just like before…

The issue in the initial post concerning the sandbox attribute was resolved.
@OMGUrOnline, your issue relating to a connection refusal will be passed onto the Cards team as well; it is unrelated to the first post. I will be replying to and referencing the following thread: Connection refused when fetching a summary card
I can confirm the issue is now resolved, and also would like to thank @jbulava, @romainhuet and the Cards team for their invaluable help.
¡GRACIAS!
