Errors when Using Live join() Functions
There is a known limitation about live queries that use
join()
functions — the details are
explained at
Join Operation and Optimization.
The limitation means that Legacy Alerts cannot be expected to work in combination with these particular query functions.
You should be aware of this when you intend to create an alert with
join()
functions, as the alert may not trigger as
expected.
The UI warns you about this behaviour before you save the alert.

In such cases, creating a scheduled search instead would better achieve the expected result.
