so if ur drawing is done,press the setting button (grey circle the bottom left corner) and then tap the paper with red arrow facing to the south,then you go to some file sharing websites like ufile.io , filebin.io , file.io , and more,remember,YOU have to save it as flipanim file.

then if ur gonna use a file,u need to find the link for https://ufile.io/ with the code at the end. then if ur at ufile tap free download and if its done you have to tap the setting button(i said where it is earlier) and press the paper with A green arrow facing the north,then you have to find the FLIPANIM file.

or i reccomend following these steps on the yt link if u didint know well
