Entering the DZ has become an issue for a lot of players. Sometimes it takes 3 attempts at holding the button to actually enter the DZ, sometimes the door isn't even there and you can see in the DZ but can't enter. Next supply drops. Since TU12 DZ drops don't happen in the non invaded DZ what's going on here
I am sorry to hear that you are not able to enter the Dark Zone consistently.
Can you provide a video demonstrating this? Does this happen at all entrances to the Dark Zone?
