My friends and i cant play with each other. We keeo getting kicked when we join each other.
Me and and other friend have the borderlands handsome jack collection version 1.02 but my other friend has version 1.04. We cant update to the 1.04 version. Ps4 version


Have you put in a support ticket?

If not, do so;

Best to do a two pronged attack on such issues.
