I was so excited about the new feature the Polish government added to our government app recently, the ability to sign documents using a "qualified digital signature", *for free*.

For the non-Europeans in the audience, a qualified signature is the European equivalent of DocuSign, except far less intuitive, far more expensive, and, by extension, not accepted anywhere near as widely. By regulation, it's the only kind that has the same power as a classic paper signature.

This feature requires an electronic ID card, and as my old ID was soon to expire, I recently got one of these anyway.

I tried doing this with two different providers, and it turns out that both of them just return a very helpful "Server error, without even an explanation of what's wrong."

As they say, disappointed but entirely not surprised.
