Notion as a company and service is amazing. The web app and desktop app works perfectly however the same can't be said for the (android) mobile app. It just doesn't work. If you type too fast, the app crashes. The menu(s) take forever to open and there's just no point of having the app on mobile. Using the mobile web version runs better than the app but the web version isn't optimized for mobile, which is the whole purpose of having a mobile app. Optimize the app and I'll change my review.
