Hi strident,
maybe that helped in your case, truly possible.
Praise the lord that you were lucky 
But after many years of research (and solving dozens of this issue) I can tell definitely that this is not the general solution.
Do you think we created this rear-hinge-2022-trilock-system-for-all-strida-versions just because we didn’t notice the plastic washer?
And how would you explain that?
It is mainly the issue which I explained in detail already here: rear-hinge-finally-the-sad-truth
Best regards,
Chris
