I created a XD Prototype and published it with my clients so that they can comment. After implementing the feedback I changed the title of the cloud document and updated the link. Now when I try to open the protoype via the link I got asked for a password which I never set. When I create a new link all the comments are gone.
you can open the link from above link or click on drop down in share mode where you can see url of link, you can find the old link from drop down also.
For second issue where you are getting password protected link though link generated my you is not password protected, can you please help me in knowing extact step and is it happening consistenly and on which OS version.
