Long touch/hold on the Album.
Thanks for the response. Yes, the above works: thanks.
Just for the record, previously, selecting the album, long pressing the first track presented an option to select all tracks to add to the playlist. This also worked in the following way. Long pressing any track below the first track and selecting all tracks would add all the tracks including the long pressed track and all tracks below.
I have always had the default tap mode set to 1+ "Add to "Now" Playing. I never change that.
This is not a large issue, just inconsistent with previous versions and provided a nice option to easily section a portion of an album.
