Problem with collaborative edition

Problem with collaborative edition

Hi,

I've done a pretty basic test because i was having issues with collaborative edition. It's just php communicating with zoho sheet

The main problem we have is, with user A and user B both working on the same document, sometimes the communication between them is not working fine, user A quits the session but user B zoho environment still flags user A as connected, and when i connect to the document again with user A, user B sees user A connected twice!

This behaviour seems to be quite random, but most of the times it doesn't work well and the document consistency is low, with possible data loss included (if user A is editing but user B does not 'see' him, he won't see user A changes on the document!!)

You can check it here:
icub.eyeos.org/prova_zoho.php
icub.eyeos.org/prova_zoho2.php

With this, you access the same document in zoho sheet with two different users

I hope i made myself clear... It's a pretty serious problem for us.

Thanks in advance!
