After bearing out whole 2 months I'm reverting to the v1.
V2 is unbearably slow, sometimes can't be resized, always dropping authentication. It seems like Atlassian got bunch of street boys and told them to code.
At the same time every other program runs just fine. Chrome, Visual Studio Code, Firefox, VM and a bunch of other programs.
Windows 10, i5 Dual Core, 8Gb RAM.
Atlassian, please do something or atleast don't update anymore, because it gets worse with every update.
