Is anyone aware of what the icon to the left of the battery indicator means? I've had this z flip 6 for about 8 months and it only just appeared after the one UI 7 update through At&t. It's only on the cover screen. Doesn't appear on the lock screen or home screen. I could only find one reference to this on a separate thread and their solution was that it indicated there was a physical SIM in their phone as well as their active eSIM, which is not the case for me.  I'm stumped. Any help is greatly appreciated!
