I've been battling with samsung to rectify this EPIC FAIL but after following up after my first oreo fail enquiry i was told we CANNOT customise text tones any more!!! I was not told why. Absolutely devastated that we are forced to put up with the same ******* tone for the countless text messages a person receives every day!!! I was the one who brought this to samsungs attention over 2 years ago with my note4 and they were grateful i pointed it out..Then this sugar biscuit update comes along with the same issue except this time deliberately...I don't know why they would take away that part of our individuality but they have I have screenshots of the conversation...For many years I've been creating personalized ringtones,text tones and all other notification tone options for friends so much that i started a small business doing so...Looks like that's a complete waste of time now...What will they remove next? The ability to bluetooth files to and from my computer or a friends Android device? I reject iphones for that very reason!!! Grrrr
