packages/core/src/js/options.ts

     * @platform android
     */
-    androidProfilingOptions?: AndroidProfilingOptions;
+    profilingOptions?: ProfilingOptions;


Can we keep androidProfilingOptions and mark it as deprecated?
We can merge both values on the wrapper init and on a later version remove it.

Sounds good 👍

Since it's marked as experimental everywhere (docs, changelog) I'm also ok to just proceed with the change.

+- Extends the experimental support of UI profiling to iOS ([#5611](https://github.com/getsentry/sentry-react-native/pull/5611))


If we decide to proceed with just renaming the androidProfilingOptions to profilingOptions in the conversation above let's add a note to the changelog

Suggested change

- Extends the experimental support of UI profiling to iOS ([#5611](https://github.com/getsentry/sentry-react-native/pull/5611))

- Extends the experimental support of UI profiling to iOS ([#5611](https://github.com/getsentry/sentry-react-native/pull/5611))

- Note that Android is also now using `profilingOptions` instead of `androidProfilingOptions`

antonis

The changes LGTM 🚀
Let's make that we handle the androidProfilingOptions deprecation/removal consistently before merging and update the docs.
