Not sure if this is a bug or expected. ISTR that moving a line around in Dynalist had no effect on its URL when linking from an external program. That doesn’t seem to be the case any more - so If I copy a link to a line into Evernote, and then move that line elsewhere in Dynalist, the Evernote link no longer works. If so, this is disappointing.
OK, just realised that links persist in the same file, but break if you move between files. I think I used to know that but just forgot
Related bug report, which we should fix soon: Moving item with links attached to it to another doc breaks links
