@adrienplg It sounds like you are looking for historical information at the individual message level when that specific message was read, but that isn’t how it works. It is more like a bookmark in a book, rather than marking off each page in a book that is read. You may have read the pages in the first chapter six month ago or 5 minutes ago, but you can’t look at a specific page and know when that page was read. Only where your current spot in the book is.
Chat read receipts work the same way.
