Replies to eBay messages when using an email client (Thunderbird) are causing HTML or CSS code from the original message to be displayed in our message, below our reply. This began ON 06/09/26 when eBay introduced changes to the messages format / interface. Nothing changed on our side and this has not been an issue for many years. Though we like the threaded conversations, the displaying of whatever code this is, is complicating the communication process with buyers. I've tried changing the sending format in our email client but it has no effect. Using the eBay messages interface directly is not a suitable workaround in our situation. It appears normal from our email client, but in eBay messages, it's exposed / unformatted code?
