Having been working on a document offline for a while, I tried copying it to the relevant folder on SharePoint- which already had the original version of the document.
When dragging my local copy of the file to the folder on SharePoint (online, at: https://mycompany.sharepoint.com), a message was displayed stating:
A file with this name already exists. Would you like to replace the existing one?
I clicked 'Replace', and saw that the file I had just replaced had "A few seconds ago" written next to it in the 'Modified' column on SharePoint.
However, when I then opened this file 'in app' from SharePoint (ensuring that it was closed on my computer first), the most recent changes I had made to the file were not visible. But, when I opened it 'in browser' from SharePoint, the most recent changes were visible. The local version of Word I have installed on my computer is Office 365 Pro Plus, and the version that is being opened in my browser is also Office 365.
I have tried copying the latest version of the file from my computer to SharePoint in various ways (drag & drop, Upload --> File, Delete the file from SharePoint and copy/ upload it again) but I am still having the same issue.
What is causing this issue, and how can I resolve it? Is it some sort of caching error?
Edit
So it's a weird one... I have just checked with a colleague- asked them to open the file from SharePoint. When they open it in app from SharePoint, they see the most recent & up-to-date version (the version I have locally on my computer, which I've been trying to copy to SharePoint). However, whenever I open the file in app from SharePoint, I'm seeing an older version. It seems that my local copy has been uploaded to SharePoint, but that there must be some sort of caching error or something, causing me to see the old version when I open it from SharePoint on my computer...
I have tried clearing all my browsing history/ data (including login data), restarted my computer, hard shut down & rebooting my computer, but I'm still having the problem when I open up.
I've also tried looking at the version history in SharePoint- I can see the latest version being when I most recently uploaded the document to the repository, but when I open that in app, it opens as Read Only, and I cant make any changes to it...
