Can’t open first email in conversation since IOS11 – Yahoo Mail - Organized Email Review

I usually use the yahoo app instead of the Apple mail app but since the latest update to IOS 11 I can’t open the first email in my conversations and it’s much slower than usual. The wheel just spins and spins. Update 12-3-17. I STILL cannot open the first email in a conversation thread. When I open the conversation I go to the last email - since that’s the oldest and needs to be read first to understand the other emails - and when I get to the top, I can’t open the newest email in that thread. I need to go out of the conversation, then go back in to read that email. I thought this was fixed, but it’s not. Also, the wheel at the top by the sponsor ad spins continually and it’s a distraction and annoying. That is new to IOS 11. Can you make that stop?
