I just started to build the first page of my app and when I preview the app on android, I see two places where it looks different in terms of style
1- bottom corners of a container are rounded only in Composer but not Android preview
2- position of bottom center circle does not match its position in Preview
This is worrying to me as this is just android and iOS could have its own rendering issues as well
Note: on web preview, it does match.
Sorry for my english. Attached some pics
