@Ane Bang Thanks for confirming. Honestly, I have ran into this myself in the past, but just haven’t taken the time to stop for a closer look. Now that I have, the issue looks to be related to any links that are later updated. Here’s what I believe is happening…
There is an ampersand in the URL. When it is saved in the back end, Miro encodes it as &
When the value is displayed in the UI edit box, it isn’t being decoded back to &. Then, when saved, it is double-encoded and we end up with &, and the link still works fine as the moveToWidget and related ID are still intact. What seems to break is the process of updating the board ID in the links when a board is duplicated or restored as the pattern in the URL is broken.
I have opened a support ticket to report the issue and update this post as I hear back.
