In my app I am working directly with the data source, no interim collection is necessary. In my gallery I only want to display the items that were created by the current user and created today.
I have tried this solution: https://powerusers.microsoft.com/t5/Building-Power-Apps/Filter-gallery-to-show-results-created-today/m-p/89589#M33895 but find that it's not working and it's not delegable.
This is my Gallery filter:
Filter('Conference Rooms', 'Created By'.Email = User().Email && IsToday(Created))
If I just use the Created By part of the filter it works fine but when I add the IsToday, then nothing is displayed.
