I switched to new teams and using it for almost a week now. Here are my thoughts:

- After switching to new teams I do not saw much ram improvements(and there was a lot of ram usage spikes) and whole expirience fell more sluggish than old teams. After a week it looks like it has stabilised and looks better

- When screen scharing have troubble with ribbon. There is now way to move it or permamently disappear and i culdn;t open a browser tab that was in middle of screem because screen sharing ribbon appears imidately.

- I do not see anything with copilot and its improvements

Issues:

-New teams do not have all recent call history at switching. I had a half year gap between my call history in new teams. After swithcing back to old teams and going again to new teams it downloaded it and now is available.

- When opening old teams(i have it on taskbar) everytime it ask if i still wan to use new teams and there is no option to "remember my choice" or something
