I have a brand new Samsung Galaxy S9+, upgraded from my S7. I never had a problem sending pictures and video by Message+ over WiFi before, in fact it was faster. But whenever in on WiFi (Home or Work) my pictures will not send. They fail every time. I have to turn off WiFi and use 4G signal for them to send. At home, that means I can't send any photos at all because I only have 1x reception there. This is enough to make me return my phone if I cannot find a configuration to fix it!
