Uploading Photos to Adobe Express

I am feeling very frustrated with the lack of a couple features that seem really basic in Adobe Express. Am I missing something? 

First, there is apparently no way to connect to Lightroom and choose photos directly from Lightroom to upload. The only reason I chose to use Adobe Express instead of Canva is because I thought Adobe products would be able to communicate with each other! This adds multiple extra steps for me and my students (I teach high school photography), and with students, every extra step is a potential misstep or point of confusion. To add insult to injury, when we do upload photos they aren't automatically saved to a library, so instead of uploading all their photos at once, then grabbing them from a library, my students need to upload one photo at a time. What a waste of time! I am very disappointed in Adobe Express and will not use it with my students again unless Adobe steps it up.
