Confused about Gemini

Hey yall! I recently got gemini pro and I am having 2 issues. Sometimes gemini just refuses to make the interactive quizzes for me. I upload my class material and tell it to make an interactive quiz, and it works about 10% of the time. I have had it for about a month and it has never had these problems before, it just started yesterday or the day before. The second confusion I have is that Gemini seems convinced that I have access to a VPN included in my subscription, but I cannot find it anywhere. It says I have access to "VPN by Google" through my Google 1 account, but it's NOWHERE. I was writing here to see if anyone has found or knows of any fixes for the interactive quizzes (it's my main method of studying pharmacotherapy/pharmacology) and if anyone knows where the heck "VPN by Google" is.

Thanks yall!
