In one of our apps, I am using child records for the user to be able to add multiple attachments to one parent record. When a user accesses one of the attachments (child records) and closes the browser tab, the link in the email to the next record, actually opens the child record from the previous record. Here is the screen for the parent record:
Here is the screen for the child record (attachment):
If the user leaves the app on this screen and closes the browser tab, clicking any link to get to the same app, but a different record, takes them to this screen.
I have recommended clicking the Cancel button after reviewing the attachment and then the next link takes the individual to the proper record.
