Awesome - thank you for this great feedback!
It might be a little bit slow at the moment because I have been working on the whole site constantly today.
Also the app does pull all the data in real-time so you always get the latest accurate metrics - which can take slightly longer compared to cached or estimated analytics data.
All issues should be solved now. Would be awesome if you were so kind to try again - everything should run fast and smooth now! Thank you very much for your patience.
