Attachment’s are not possible

Hi,

I am big fan of gmail app. I configure gmail,by company email everything.but i was doing those on my android mobile.
After switching to ios , initially i thought gmail app would do the same. But it came to picture on a situation where i need to send some attachments from my iphone and it was not possible. This is kind of basic functionality to me , i used to attach images, documents often for my business.
This made me to have bad review and uninstall.I dont know how other users are using this app in #ios.please advise, if someone found a way to resolve this.Thank you.
