Chronos Planner is still in its early release, so there will likely be quite a few bugs outstanding. If you believe you have found an issue, please email us at support@bosc.app along with reproduction steps and any applicable screenshots, where possible.
Apple has a helpful guide to taking screenshots on your Mac that you can read for more details on taking and saving screenshots.
Thank you for all of your help to make Chronos Planner as bug-free as possible!
