We are having lots of problems saving on documents created in Zoho.

We are working on documents that were created in Zoho and when it comes time to save, after a short or long time, the changes are not being reflected in the document and a lot of work is being lost and then repeated.  This is happening from a variety of computers, different times of day etc.  Thanks for any guidance you can provide.
