Hi @jdetrolio! Have you updated to version 2.11 on your Mac yet? We updated the link format in that release, so any newly-clipped messages should open on Mac and iOS. If you’re still not seeing the right behavior, please drop a note to our Support Humans and we’ll investigate. Hope that helps!
Glad that it’s working with the update! I’m afraid I have no straightforward and safe way of converting the old URLs (the search field doesn’t search inside encoded URLs, otherwise a Find & Replace would be in order). Sorry!
