Generally looks good to me! Ill let Niharika give the official 👍 though as she is leading the project

[cbullinger]

@niharika01 this PR includes some unrelated updates (formatting cleanup and corrections I made while I was working in these pages), so not everything will need your review. I've left comments to indicate the updates specific to collections in mixed project that I'd like you to take a look at.

LGTM 🚀
Thank you!

[lindseymoore]

A few small things!
Larger question: Should the 'Realm Object Schema' be referred to as 'Atlas Device SDK Object Schema'? I see you switch between using the terms depending on the page; should probably be standardized.

[lindseymoore]

Overall, LGTM, and thanks for making these updates!
Not sure why some of the :manual: links are giving 404s on my end. If it's working on your end, perhaps just do a quick check to make sure they're working once deployed.

[niharika01]

Thank you for updating this! I think technically this was out in prod on May 29th but I'll defer to @tkaye407 since May 22nd was the official release date
