Apple's native 'Mail' app not showing attachments

Yes, I understand the image has to be downloaded to my phone to be displayed. I also already stated that above. What I am. saying is: In practical matters, the mail app is not displaying the attachments. It is showing there are attachments (there's a clip icon on the top right) but:

1. It doesn't show the attachments
2. It doesn't allow any easy option to open them or view them (just the first image you see there)
3. It doesn't show how many attachments are in the email, which could potentially mean I could delete emails that have attachments that I haven't seen.

Again: I know that phone has to download the images to render them. This issue doesn't just apply to only images. Moreover, I don't want to navigate to the temporary files folder that's hidden who knows where just to see an image or a file that could just be shown directly on the mail.

That image you see there is not on my phone. Maybe it is stored as a temp file to be displayed, but if that's the case then why the app doesn't show the other 3 images that are attached there? Every other mail app does that and it's pretty convenient.

The big problem here is, when I first saw that email I thought there was only one image. I almost deleted the message since the first image is totally useless, but the other ones were not. I could potentially disregard important documents and pictures because of this, and since there is no easy way to know how many attachments are in the mail either, then one would have to be wary of absolutely every email, regardless of its importance.

You are right. I am actually using another email app for this reason. I was just reporting the issue since many of the features in the Mail app are actually pretty good, so the app definitely deserves its place. I was hoping there was someway to configure the app so that it shows all the attachments, but anyhow, thanks for the help
