mobile coding issue?

wasnt sure where to post this!!!!!

so ive been coding from desktop and i went to add something to my movies list while on mobile. i noticed the about me section when editing on mobile was empty, and didnt think anything of it.

when i saved it, i went on my page and about me was missing.

just got home and checked on desktop it was still missing. thankfully i had the page still up with my original coding and fixed it.

just worried if this is gonna continue to be an issue, and if anyone else has experienced it? not sure if its my fault or what. lmk
