Updating field from the UI or from function take more that 1 minute to be updated

Updating field from the UI or from function take more that 1 minute to be updated

I have activity order model with dropdown status field, I've changed the status from Completed to Canceled on the CRM like on the attached image:



But once I fetch the record on function the record didn't updated behind the scene

The strange thing in here that I can see the record has been updated on the CRM UI but if I fetch the exact record the DB is still the old one and not the updated one.

And this can be take up to 2 minutes sometimes

In this case once my client cancels the activity order he doesn't see any changes on our client app.
Also this causes me many troubles on Zoho Creator. Once the client cancels the order I run a function on Zoho Creator to update the number of the activity participants can join by fetching the CRM activity order but some of these have the wrong data behind the scenes !!!! 

Need you emergency help
