After applying SQL Server 2016 SP1 CU3 to a reporting services native mode instance, selecting any paginated report in "List View" results in the error message "Could not load folder contents" "The folder "report/reportpath" does not exist. IT could have been renamed, moved, or deleted." (where reportpath is the full report path).
Selecting the same report whilst in "Tile View" works fine and does not raise the error.
Removing SQL 2016 SP1 CU3 and reverting to SQL 2016 SP1 CU2 fixes the problem and the report loads correctly in both "Tile View" and "List View"
