I am using Zoho Sheets to edit files stored in Google Drive.  Sometimes I am doing something, putting new info to cells, or adding sheets, anything, and then I reopen file ooops  my work all gone nowhere.  Can that be a problem of Google Drive?    Or what to do?  I understand when no connection then Zoho tells me - no connection reload, etc

  But everything looks ok and then boom - do your work again...
