Checklist

• Words are spelled using American English
• PostHog product names are in title case. It's "Product Analytics" not "Product analytics". If talking about a category of product, use sentence case e.g. "There are a lot of product analytics tools, but PostHog's Product Analytics is the best"
• Titles are in sentence case
• Feature names are in sentence case. It's "Click here to create a trend insight" not "... create a Trend Insight" and so on.
• Use relative URLs for internal links
• If I moved a page, I added a redirect in vercel.json

approved! but the changelog / releases do not make it clear why 5.12.0+ is required, maybe a quick note about that would be good?

JS SDK documents this on this page https://posthog.com/docs/session-replay/how-to-control-which-sessions-you-record
Android and iOS documents under the privacy page https://posthog.com/docs/session-replay/privacy?tab=Android

i think we should move the android and ios docs to the "how-to-control-which-sessions-you-record" page and add code snippets per platform similar to the privacy page, with tabs.
and move this to that page as well

right now we're gonna have the same content in 3 different pages
