See reply no.9.
First I also got blank page in firefox, but after several login attempt I got a page said firefox can not understand the link and after a good time of search I got this post.
UnityHub 3.0 beta release is a disaster. Worst experience ever. Whole night was wasted on this problem.
As a former robotic industry software developer I really hate any software developer force you to update your staff, because “if every thing seems work then DO NOT UPDATE!!” is FOR A REASON.
And unityhub become one of them.
Back the day I was using windows, I forced unityhub to not update. After this unexpected-because I’m not joining UNITYHUB BETA- accident, now I’m going to FORCE unityhub to not update again.
