Ok so I have an issue. I have AT&T service and cannot send a pic/MMS over wifi to my wife's Note 10 plus. When I attach the pic or mms it shows actual size and takes 5 mins to send. When the send completes after 5mins, it actually compresses the image to finally send. When I use cell service and attach it does not compress at all and sends instantly. Now, when I attach a pic/mms to text any other device (iphone or other android) it attaches and instantly compresses and sends over wifi. I did not have any issues with our previous Galaxy 8s. After spending hours with AT&T they said its a samsung issue and suggested I just send over cell service. Samsung support blames AT&T. This makes no sense to me at all. It does not matter what wifi I connect to it will not send mms from note to note but is fine any other device. Any suggestions or is anyone else having this issue?
