UPDATE 21/08/2014 – I have been informed that this occurs also on Office Mobile on iPhone

Recently, I discovered that the SharePoint Online site content displayed on Office Mobile – running on Windows Phone 8.1, it not correctly updated, still showing deleted items or wrong items numbers (as shown below).

This occurs even if you remove the site from Office Mobile and then re add it.

I initially saw it while running the Developer Preview of Windows Phone 8.1 – so i thought is was a messy bug from this beta version, but as I’m now running the full RTM version, this is not anymore a beta bug Smile

A service request to the Office 365 support team is currently opened. I’ll update this post as soon as I will have a solution, answer or any additional details regarding this issue.
