Hi,
I'm sharing dropbox with my work colleagues. Dropbox is in the network folder and is being shared on the work network. We're all on Windows 11. Everything has been working fine until recently when it seems we are not seeing each other's updates on files and folders since the beginning of July. Below is some screenshots of what we're seeing:
In the 2022 Folder I've created a 2023 folder on my computer:

In the same 2022 folder on colleague's computer is not showing the 2023 folder:

Similarly, on my colleague's computer you can see a folder called July:

In the same folder on my computer, the July folder is not showing:

Lastly, a file I worked on on 11 July 2023 which you can see in the date modified column on my computer:

The same file on my collegue's computer shows as the 2019 version:

What could the problem be? Please help.
