> I noticed that all of my Messenger notifications stopped including the text of the message

Isn't that a preference in the notifications setting? "Show Previews" gives the options of "Always", "When Unlocked (Default)", "Never". Perhaps it's just defaulted to "When Unlocked" after an update?

I did just check, and it is set as "When Unlocked (default)". The unlocked screen does just show a no-preview Messenger notification, the actual preview text seems to be being provided to iOS as "<name> sent a message".
