Mail shows paper clip but no attachment icons to open at all
Hello everyone. I'm having the hardest time finding what's going on and after a few tiring hours of surfing the web I found nothing like my problem. So I decided to come here for help. I hope it's not something stupid I'm just missing but if that's the case I apologiz in advance.
As you can see in the following picture I got an email with an attachment, as you can see the paper clip on the left
When I open said email I go to the bottom of it and find no file icons to open!
As you can see for the same email but using the Gmail app, there are four pdf files attached and, as far as I know, pdf is a compatible format to open from Mail native iPhone app
Can PLEASE someone help me see what I'm missing? I already tried signing out and in again, reloading all my emails but nothing different happened. I'm about to pull my hair out here!
Thank you all for takin the time to read this.
