PRIV plugged into computer. Option to transfer files no longer appears
I tried to transfer photos and other files from my PRIV to my computer today. I have the correct driver on my computer and after Marshmallow, when I plugged it to the computer with a usb cord, I always got the option to choose transfer data but now the option does not show up anymore, but only the charging light up the side of the screen as soon as I plug it in. I am using the same computer as before. The BlackBerry icon in Windows Explorer shows but it will not open, of course. I know it has to be opened from the phone by choosing the option to transfer files and data but without the option I am at a loss to know how to get it to happen. I have done a hard reboot and nothing has changed. My plan was to upgrade to a larger SDcard because the current one is almost full. I wanted everything that is one the old one put onto the new one. I also wanted to go into the internal memory to check on photos and downloads that should perhaps be removed.
