Powerline does not track git branches

Stuff:

• WSL2:Ubuntu 20:04 LTS

• Bash / FishShell

• Powerline installed using sudo apt-get install powerline

Problem:

Powerline does not changing dislpayed branch after git checkout <branch_name>. When I do git branch, git shows me that I have switched to the branch but powerline still displaying the previous one. When I disabled powerline from shell config, then branch switching is corectly displaying. I have tried with new created user and it's the same, so it's not problem with .bashrc/ config.fish. Funny thing is that in vim, powerline works correctly. Any hints what can I do and check ? Reinstall powerline does not helped ;)
