I recently transferred our site from the dev agency managed instance on Azure VMs to our own Azure subscription in a Web App. Everything appeared to be working correctly but now some fundamental functionality of the platform has stopped working. When entering dates with "Date picker with time" it is not recording the values entered, which is stopping all users from creating content.

I don't know what is happening here and am trying to diagnose the issue (legacy code so I'm still figuring it out). For some reason when entering a date and time, it just passes an empty string. This worked fine last week before we transferred the hosting to ourselves but none of the code has changed and the database is the same....

Thanks,

John
