Re: The flow cannot recognize if the email has attachment or not
Hi @Anonymous
I know it's not like this in my post but try the below, just in case

Also, look at the run data for "When a new email arrives (V3)", look at the JSON output (or post an image back) to see if the "HasAttachment" is reporting as true or false, it looks like there is no attachment but I'd be guessing untill I see the JSON ouput.
If you have found my post helpful, please mark thumbs up.
Any other questions, just ask.
Thanks, Alan
