Why is session data disappearing after launching a new theme?

[sipajones]

Since launching a theme in October, our session data appears to be disappearing. No issues with orders or other data, and this isn't reflected in GA.

Session data for the 19th November showed at a normal amount yesterday, the same admin home report today show's it's disappeared... any idea what's happening?

Today (21st):

This is a problem from Shopify`s side
