A DEVONthink annotation link should look like this one (which is an actual working link to an annotation on a PDF stored in an indexed Obsidian vault – i.e., the same context of the supposed problem):
x-devonthink-item://0EA29BC7-4D7C-43FA-8A1E-00DB7D02694E?page=0&annotation=Text&x=1101&y=5789
So, your link “should” work assuming alotofdigits is the same pattern. And, if it doesn’t work, then you changed something. The most current version of DEVONthink is still working just fine with respect to annotation links.
Easy to fix. Go back to the pdf & annotation and copy another annotation link. If either the PDF or the annotation is missing, then nothing will work.
(BTW, you don’t need to hide the digits. There is nothing about them that anyone could decipher to figure out your private stuff.)
