PS tutorials and temperamental “learn” button

Hello, I am a CTE and Art teacher in Seattle and we are currently struggling with the Photoshop tutorials. I am using Google Chrome, on desktop computers newly purchased by my district. I am having issues with students seeing the “learn” button and being able to access the same tutorials in the same way which is key for teaching a class of 30 students. We’ve tried resetting the workspace, next I am going to try Purge and purging all. What else do you recommend? IT support in my district does not know how to use the program…
