Delete / Update review links

I can’t seem to update shared links.

My document has 3 artboards. One is from an old document that had already a shared link (Design Review setting). Two artboard are new. 

I want to provide my client with a new link where she can see all 3 artboards. But I can’t seem to get rid of the old links, and I can’t find a way to combine all 3 artboards for sharing with one new link. All I can do is create new shared links for each artboard indivudually.

I did delete all shared links on Creative Cloud (assets.adobe.com) aldready.

Am I doing this wrong? Am I missing something?

Thanks everyone for help.

(The screehsot shows the 3 artboards, with two links "Page 1" and "Page 2" which I would like to delete. To then be ablte to group them into 1 new link for sharing them together.)
