When I send out a link to a shared pdf review, the link gets truncated. All the characters in the link appear in the email, but when the link is clicked on, it only has about 1/2 the characters. Local IT has looked into this and can't seem to find the issue. The file path described in the link text of the email will lead people to the file--assuming people are able to follow the path.
We currently host our shared pdf reviews on SharePoint Online--but we have had this issue prior to moving to that platform.
If you're using Microsoft Outlook to send an email message for notification, try inserting a hyperlink into the message instead of just typing (or copy/paste-ing) the path and filename into the message.
Alternatively, maybe you can create a .txt file that has the path and filename on one line and attach the file to your notification system. Recipients can open the file and copy the location of the path/file into their file browser.
