installing dropbox

iOS and iPadOS

Hi folks,
I deleted dropbox yesterday to get rid of temp files that makes the app larger, Now I'm trying to re-install it, but it stops as soon as it gets to 10 percent.
Been trying since last night, but no change.
Restarted the phone as well by terning it off normally and also by holding in the power and home buttens.
Also reset my wify.
Thanks in advance for any help.
