Well, Mistertango operates under Lithuanian law and if the law says outdated ID document is not valid, don't think Mistertango alone could change here something.
<sarcasm> Really man thank you so much, I couldn't guess it alone </sarcasm>
If you took the time to read the topic, I was first asking if MisterTango is accepting ID cards like I was describing. Then @aesma replied to me that for example Italy wasn't aware of this and could turn French people around at the border. I then, in the discussion, replied to him that's it's not true and explained why. (There are no more borders in Europe since more than a decade by the way

)
In my last reply which you quoted I clearly said: "Since my previous post, I found that Lithuania is one of those countries refusing those outdated cards"
So trust me I can guess alone that MisterTango is not able to accept those cards
