@PinkBluebonnet That's odd if it's just one message & you tried the app, mobile, and desktop. Normally you could try a different browser and/or delete cache/cookies. But maybe there is something else wrong.
Are you getting the email notifications that there is a message on Etsy? If so, technically the customer's message is still within the email notification, it's just hidden in the code now & not visually displayed. In your email app, you can "View Source" then scroll through the html to read the customer's message. If it's a repeat customer, you should have their email on a prior order. So you may need to email off Etsy.
