I have been looking internet for days. I haven't seen anyone to note this solution I found. I found out that when I scan the app I connect my phone but after minutes that nothing won't happen and I have to tab on the close icon I my phone, the phone session was gone. Therefore, last time I didn't tab on the close icon, I just went to my phone menu and closed the Opera app completely. just this! it worked for me. I signed up here to share with you. because I had been searching and it was important to me.
