@LilbitofblingByNancy: There are many many reports of this in this forum. There appear to be a number of issues affecting Messages at this time and what you are experiencing is one of them.
"The notifications for new email messages is not working on my Etsy Message page." This is a user interface issue (annoyance) and does not seem to have any other side effects.
That being said there have been some reports of replies disappearing particularly for app users.
Always best, though, to keep an eye on the CSV file on your Star Seller page to make sure that replies are being logged correctly. When you look at the file remember that that the dates / times are in UTC (not your time zone), only the first message of a new incoming thread is included (all that counts for Star Seller), and usually a new incoming thread is not included until after the 24 hour reply window has passed regardless of when you replied. Star Seller stats (and the CSV file) seem to be updated only once per day so there may be an additional day's delay. There is also a link to the actual message thread so you can verify if the data is correct or not.
