I rec'd your response to a previous problem I was having but you closed the comments on that response and you suggested a solution that is not possible.
If I respond to an email with "reply" and start typing and then realize I need to "reply all" there is no option to click this anywhere on the screen. The response I rec'd said to just hit the three "reply all" arrows but there is no such thing once I start the email by just hitting "reply".
Here was your response to my previous issue that still exists:

The reply all button is next to the reply button. If you hit reply and decide to reply to everyone simply click on the reply all option (double arrows pointing to the left) If you are still having issues follow the troubleshooting steps from this help article: https://help.yahoo.com/kb/SLN3223.html
Still waiting on this issue to be fixed. Please rectify ASAP. Would be a huge time saver!!!
Still waiting on this issue to be fixed. I consider it an urgent one as a business owner paying for ad free email.

We are not talking about the Reply All *button*, but the "Reply All" prompt at top right of the message after you've clicked on "Reply", which has vanished. It was much needed, as a reminder that the person you were replying to had cc'd other people in on the conversation and you were about to leave them out of it. Without it, I've either got to be far more alert, close down my "Reply" reply and start a "Reply All" reply, or go back in and retrieve the sent email so I can forward it to everyone else. All these options are more time-consuming.
Still unable to find a way to reply all, without going out of email and back in, once I have hit reply by mistake. Also, I cannot add emails manually because the body of the email still does not show all of the contacts that were included in the email I am replying too. It only shows one email address regardless of reply or reply all. As a business, I need that info to show in the body.
