Missing Titles in ‘You’ List Searches

Several times I have not found titles to add to lists in the ‘You’ section that are available when searched elsewhere. I can’t understand why they’d actually be in IMDb and not accessible everywhere. It would be very accommodating if there were an ‘Add to List’ option from the main search page rather than having to select ‘You’ to get there. It would also be great if there was information on every title as to where to stream each title. THANK YOU.
