idk why, but the mobile app has taken away the ability to start comments on paragraphs. if there's one already there, then I'm able to click it. However, if it's not there, then you're out of luck if you're on mobile. Anyway when the butler say 'compabilites' did you mean to type "capabilities" ?
I'm glad that you caught that. Ever since they updated the mobile app, my editing process has been flawed, and minor mistakes like that slip through. If you manage to catch any others, then pointing them out would be helpful. I'll try to find a way to better proofread and edit away many of the mistakes.
