hi. at least this happened for me.
i had an update notification for my facebook app which i had
side-loaded a couple months ago. when responding to the notification,
i was directed to the google play store to update. i signed into
google play and was able to update without changing my security to
apps from unknown sources.
there are a number of improvements. and, now, i'm looking for that
livestream button for my fb page /smile.
anyone else notice this?
stay well ... william
