Steps to Reproduce

Previously in V7.116.0, distribution tracing was working and we could see the distribution of our resources in transaction performance Sentry UI.
We migrated to v8.3.0 due to the profiling feature as it was not available in the older version. In the Older version, we were having custom instrumentation with startTransaction to start any user activity.
Now, in the new version, somehow we can get the same kind of behavior using startSpanManual, but "operation duration" is not showing any value and its respective child and parent span is also not capturing any data in Sentry UI.

Expected Result

Previous data in Sentry UI was happening automatically and no major action was required to capture any operations. It was happening under the hood.

We are looking for the same kind of data capturing that was before in V7.116.0.

Before Result

Now in V8.3.0

Actual Result

Expecting to provide if we need to add any config to get this done.

Looking to get the same result as before
