I just tested with the Filter of a SharePoint list gallery in my app and it works just fine. The gallery will only show the right items after I put some letters in the text input box. What is your connections in the problematic apps? Also please try to recreat the apps to have a test.

I think this may be related to another issue I posted with the DataTable,
I just changed the Filter from a dynamic value , variable rStatus is set based on user selection, to a hard coded value:
rStatus can equal one the following: Pending, Approved, or Rejected
Filter('SPList', Status = rStatus)
Each of the following Fail with the WebAuthoring abnormal termination:
Filter('SPList', Status = "Pending" )
Filter('SPList', Status = "Approved" )
Now when get to this point, the DataTable shows nothing even though I change the Status to either of the above or back to the variable rStatus. This is a new session due to the WebAuthoring abnormal termination.
Filter('SPList', Status = "Rejected" )
SessionID: No Session ID given, and it never Filters.
Also I published this version and launched it into Dynamics365, this now shows the Red Error bar that the O365OfficeUsers.Manager and O365OfficeUsers.MyProfile are throwing errors?, this does not happen in development mode.
But now the DataTable will Filter once and ignore other calls to Filter.
