See more than 100 photos from Lightroom album

Hi…hope someone could help…or point me to the right direction, I’m trying to import a set photos to make a collage in PS Express, (also I tried in Adobe Express mobile app) however it looks that the system only retrieve a view of the first 100 photos from a Lightroom album, and I need some of the ones not listed or previewed, is there a setup or view mode that allows me to see all photos in the album no matter the quantity?
