Is there any problem on the message system?
This month I have sent 3 messages, 2 to buyers (about shipping issue, since the airmail service is suspended in many places due to the COVID-19, I need to ask them if they accept posting by surface mail, or they would wait for the airmail service to resume) and 1 is a reply to a question. So far no one replies at all (one message has been sent for nearly 3 weeks, and I re-sent but still no reply). Keeps me thinking if the receivers can get my message at all. Any one has the same experience, and what can I do?
