Date Field Drop Downs not appearing in Web Apps

[FPCWAGIS_Admin]

We have a series of Web Apps that we've been using for a while now without too many issues....until now. For some unknown reason (and we haven't made any changes that would cause this), the date fields in the Batch Attribute Editor in all our Web Apps have lost the ability to select dates from an interactive window. Previously, you would click in the box and a date selection popup would appear. Now, no popup and we can't event type the date in manually. Has anyone else come across this?

Should look like this (ignore the field names - stole this from the interwebs);

But looks like this (Entered in GeoMaster is a date field);

For anyone else who comes across this, ESRI have identified it as a Chrome specific bug (after a recent update to Chrome) and are working to fix it. If the Web App is opened using Firefox or IE, then it works fine (frustratingly).
