The so called "message box problem" is actually several problems related to messages.
Reminders do not appear in chronological order (so for example, if you send yourself a reminder about a patient to appear 5/22/2019, it appears farther up in the message cue, perhaps two weeks earlier and out of sight).
Sometimes messages when forwarded appear to be blank. This most consistently appears for us when I send a message to staff and cc myself (so that I can then send the message to the patient's chart, to document that I made the request).
These were supposed to be fixed in 10.1.4 as well. I know that not everyone noted these issues; I wonder if they have actually be corrected.
