Why downloading/opening attached files on emails takes too long?

I have recently bought Blackberry Keyone Black Edition to substitute by previous Blackberry Passport working on Blackberry's OS. However, i find the problem of downloading/opening files attached on emails very annoying. it takes a lot of time for this to be done no matter the size of the attachment. With my Passport that was only a task of very few seconds.

Can anyone help me in that?

Hello

Go to HUB. Select 3 lines top left scroll down and select settings. Now scroll down to your email accounts and select. Scroll down till you see Download attachemnts make sure it is toggled ON. You must do this for each email account you have set up on your KEYone.

Good luck
