Ottima app per imparare!

I like this app so much, I want to work as an animator in the future and this app is helping me a lot.
But when I want to save a video in my gallery the app says that I have to unable it in phone settings...I cant do that because the app never asked me to use my gallery so its not in the list.
Maybe its just me, but if its a problem of the app can u fix it please? Thank you!
