Hi Tomas, my sincere apologies about that, for the UI that shows which dashboards - I was thinking about more of a “Manage” page where you would see where they are located and be able to delete them too based on the previous question about deleting visualizations. Again I’m very sorry for the misunderstanding.
The API resource you mention, again this was my mistake and I overlooked this available resource 😕
If I can provide some better news to you from my side, I am happy to report that bug mentioned initially is being worked on with high priority and a fix for this issue is currently being worked on. However, at this moment I cannot provide you with any ETA on when the fix will be rolled out, but I will provide you with more details as they become available.
