IsBlank function not delegable?

Question

I'm trying to filter out rows on a particular column being blank. It doesn't seem to be delegable. I'm using sharepoint list as a datasource.

Answer 1

It may be worth to try this:

Time_Out=Blank()

I have found in some cases that this may be delegated whereas IsBlank() is not.

This is not documented anywhere, PowerApps documentation has a long way to go.
