Hello everyone,

This week’s release focuses on reliability. We fixed an issue that left the Polar Sleep and Polar Continuous Heart Rate data sources empty, made exports more reliable when filtering by survey answers, and corrected scheduling for weekday time windows that cross midnight. Details are below.

## 🐞 Bug Fixes

### Polar Sleep and Continuous Heart Rate Data

We fixed an issue that prevented the Polar Sleep and Polar Continuous Heart Rate data sources from receiving participant data. Both sources were coming through empty even when participants had recorded and synced sleep and heart rate data. Researchers can now receive and access data from both sources as expected.

### Export Failures When Filtering by Survey Answers

We addressed an issue where exports could sometimes fail when the Filter Box was used to filter by survey answers. Filtering by survey answers is now more efficient, and exports complete more reliably.

### Weekday Repeat Windows Across Midnight

We resolved an issue with triggering logics that repeat on selected weekdays, where a time window crossing midnight, such as 10:00 PM to 2:00 AM, was scheduled incorrectly. Sessions now keep the full window.
