We have Zoho Analytics connected to GA4 to import daily event data. This has been running without issue for a couple of years.

However, a month ago we started noticing discrepancies. All data until October 10 lines up perfectly - October 11 onward is all incorrect (approximately 14% lower pageviews in November). 

This is observed across different properties in different google accounts, but all being imported into one single Zoho Analytics workspace - all of them are off starting October 11, so isn't just that one config was changed somewhere on our end.

What is the cause of this and how can it be fixed? If the data doesn't line up, we can't trust the Zoho Analytics data, and all of our dashboards are useless.
