m0useanswered grow question 10 months ago I have the issue where if a business messages you on chat. it highlights the main chat icon in the lower right as "new chat" with the icon turning green, but when you open the window it does not say its on the business side of chat. no notifications, but it does do that on the common side of the chat with users.
They are working on the issues, just slowly and they classify some as solved when they are not. just keep emailing them, do it once a week till its solved and add on any other errors you see. I wrote them a long list of fixes then realized in not being paid to bug report for them. They should have tested the site "updates" in a sandbox before going live.
