Error conditions in “Unread Messages” view – Salesforce Inbox Review

This app is very hard to use because I get so much email and frequently I need to see messages that are unread but have scrolled down the screen. Unfortunately most of the time when I try to open up a message from the “Unread messages” view it gives me an error that it can’t open the message. I’ve reported this directly several times over the last few months and nobody has addressed it with me or even checked with me.
