Haven't tried dark mode too much yet, but definitely like the option for when it's late night etc.
Honestly, not a fan of the new bubbly PM layout. Personally, I like my emails, texts, PMs, etc. To be simple and straight forward (like it was). I have to scroll up and down hunting WAY too long on my android for PMs like this.
I'm hoping there will be an option to revert back to being similar to older style for this part.
