Just downloaded Spark Mail again, as I do every few months, and see for myself that copying an email link does NOT show the email subject. For whatever reason, this DOES work with the older version of Spark, so will revert back to that again. There is a bit of an oddity with it, in that the email has to be in the Inbox. If it has already been archived, it won’t work unless I move it back to the Inbox (which is what I do temporarily if I need to get that link)… I just emailed Readdle again with the request (and link to Hook), for whatever little that is worth at this point…
