I use Dropbox on my Windows 8 laptop at home and on my iPhone 5c.
I have a particular file which I’m trying to access from my iPhone. I saved it on my laptop last night (3rd November); the version on my phone is dated 26 October.
Other files which I saved last night on my laptop are showing with yesterday’s date on my phone.
It’s an .xls file, approx 68kb.
