Functionality Issues’

I am a thirteen year old kid who is constantly getting bigger by my parents to check my grades and prove them to my parents. But recently, my phone glitched and I had to delete and reinstall the app, but when I go to select an organization after opening app, it will not let me select it, and will not click the button every time I go to click it, and I cannot view my grades or anything because I cat get in and this is so frustrating!!
