Is there a known issues with this setting? I had to turn mine off recently because with it on I was not able to receive messages from some people. I have a Galaxy S9 plus. I was having text issues with Note 8, Note 9, and an LG phone.
Since Pie 9 update, I have no read or delivered receipts, no text dots as ppl are typing a reply back to me and the blue dot that's beside a contact name when they are active on phone. Need these features back, PRONTO!
I have a s9+. I'm having issues with advanced messaging as well. I also can't send any pictures in my messaging app. I talked with a tech from Samsung last week and he had a phone like mine in his hand and tried to use this feature and couldn't. He then told me he would be talking to his supervisor about a new update that would allow us to use these features again. Hopefully that will be soon.
