Good afternoon,
I already reported in the review on google play this bad bug on your product.
adobe acrobat for android 20.
after wrting a note, a comment, the text is lost if i touch the screen.
there is no pop up window to ask if i want to save before to exit.
if i don't press post, the writing is lost.
lost
if you browse the document or touch the screen unintentionally you loose all.
imagine writing with a pen on a paper, and if you touch the paper all the writing is lost.
i think this is not a difficult fix
i hope you can do that
thanks
youn
