i mean, yeah its a private beta but this isnt the first round of betas for Division 2 and these seem to be the same issues in the Division 1 beta. I myself have played some betas and this is the worst one I've been in barring when server stress tests are done but thats what that test is for.
for me, the huge issue im having is Delta 3 so I cant play with or against people since I would just disconnect right away and my internet test is stable.
