Okay, update: also on my MAC the right-mouse-click (and getting a link from a image of text-box) does NOT WORK anymore. What are you doing over there at Miro? This is even more annoying. Now I'm not able to place any reference links to the information on my boards at all. 
Very likely I'm not the only one experiencing these problems. Hope you will fix this soon!! 

Regards, 

Bert

Wondering, as a quick solution for now. Is there also a way that I can copy the link of a text box or image with the key combination on the keyboard?

Hope somebody can help.

​@CryptoBert If reloading the current board doesn’t temporarily bring back the context menu after using the ellipsis, here are the shortcuts (replace Ctrl/Cmd, Alt/Option as required):

You can also use the  Link to shortcut (Ctrl/Cmd + Alt/Option + K) and then select the object you are trying to link to:

This problem is happening to me too - when I click on the 3 dots for 'more' nothing appears. It’s a huge problem cause I cannot unlock some of the frames, pictures, etc

I’m finding this issue intensely frustrating, almost to the point of making Miro unusable. I did the workaround on Tuesday (the last time I used Miro), but have found the same issue today. So do I need to do the workaround everything single day until the bug gets fixed? It’s a bit surprising the issue is still ongoing after 23 days.

Just back from being off for 3 weeks and 3-dots works FINE :-) 

Thanks for the fix, however it was done…

Not for us, we still experience the issue. Refresh or clearing cache/cookies seems to help at least temporarily, but still waiting for proper fix.

​@Martin Haustein Still happening for me too.
