DataSore does not return any result when cursor pointing to entity gets updated but retains its position in list #2427

I'm using google datastore to get data of a user:

This is what i'm trying to do:

1. When data is updated, its updated_at [indexed] property gets set to current timestamp.
2. I query data on updated_at in ascending order and store cursor returned for later use.
3. Now user has updated the last entity (which cursor points currently) and no other data is added or updated.
4. Now i'm expecting that last entity to be returned in next query (using that old cursor) because it was updated and now has a new updated_at timestamp.
5. But that is not the case, i do not see that (my result is empty list) And now i have lost that update completely because query will return all the other object except that last entity that was updated.

• I'm is doing something wrong or this is the way it is?
• If this is natural behaviour then what is preferred way to get that last entity that was updated?
