Highly recommend checking out wefwef - closest option to an Apollo clone as I’ve seen so far in terms of UI and functionality, and doesn’t even need to be installed. Memmy is a very good second place option, but I’ve been using wefwef since I heard about it yesterday and ZI think it’s better.
Are you using it as an installed PWA? I’m not having any issues with animations or scrolling. I have run into a few weird UI bugs with slide up menus within communities, but that’s about it.
