Cross app query doesn't work

In the past, we can do cross app query like the example mentioned in this articles:

https://docs.microsoft.com/en-us/azure/azure-monitor/logs/cross-workspace-query#identifying-an-application

 

Not sure starting from today or this week, it doesn't work anymore.

It will always result "no result found from the XXX hours", even it DOES really have data if I go directly to the particular application insight to query.
