 # Changelog
 
+## Unreleased
+
+### Fixes
+
+- Keep UI profiling running when `startProfiler` is called before a requested stop takes effect at the end of the current chunk ([#6291](https://github.com/getsentry/sentry-java/pull/6291))
+  - Before, the start call was ignored and the profiler still stopped at the end of the chunk, even in `TRACE` mode while sampled spans were active. On API 34 and lower, every later profile also stopped after one chunk.
+
 ## 8.61.1
