Failed to import construction plans since last update.

[12Insight]

As before, I copy and paste the content of my constructionplan.xml into an input field on the website. But now when I click the Import button, I see an error "Failed to import plans".
My previously import plans in Layout load fine. But if I delete them and try to import again, the same error occurs - "Failed to import plans".
I have tried to import plans from Windows desktop browsers such as Opera, Google Chrome and Microsoft Edge, but it doesn't work either. It also doesn't work with Android browsers.

Can you add the XML here so I can have a look? Thanks.

Some of these plans are mine, others I downloaded.
