Hello Matt, May I have your MyASUS APP and ASUS System Control Interface V2 driver version? You may enter the "Link to my asus" app on your phone, and check for "allow permission" again, to see if SMS part is granted. Thank you.
Hello Matt, okay, because I don't have your phone model either. Other Android phone I have are working fine. Was there any firmware update on your phone before this issue occurred? I will consult more about your issue. Thank you.
