i think i know what he is saying as i have the same issue. when using note 4 and note 7 i was able to use the (google keyboard) GBoards options to search and find gifs when sending text messages from the GBoard App. example, hit the GIF button at the bottom type in WOW and get an animated gif of wow....If i install the GBoard keyboard app now, it does not allow you to do it with the S8+
