dates not working in Zoho CRM

dates not working in Zoho CRM

My team and I use the latest version of Google Chrome and all use the Zoho one Enterprise Edition. We've noticed in the last week that dates have become unusable within Zoho CRM in Chrome. When looking at a list of leads for example the last activity time shows as "undefined".  
When we try to edit a date, no matter how we write the date format, it says "Please enter a valid date" (We are writing it in the correct Zoho format Mon DD, YYYY).

Because we do not have use of dates in Zoho CRM, we cannot schedule tasks, or schedule emails, and we cannot look up the last time we made any edits to a contact or lead or any entry within our CRM. A CRM without dates is becoming unusable for us. 

Please let us know if there is a fix for this
