Bug.

For future reference please refer to https://forums.garmin.com/developer/connect-iq/w/wiki/5/bug-reports-faq#new-report for the kind of information that is required for a bug report. This is really just a question, which I would generally recommend you direct to the app developer.

That said, if you look in the app reviews for Kite Woo, you'll see a developer response that includes a link to the bug report for the issue you're asking about: https://forums.garmin.com/developer/connect-iq/i/bug-reports/bluetoothlowenergy-bug-in-the-latest-instinct-2-firmware. Following that link, you'll see responses from users on beta firmware that contains a fix, so a fix is coming in a future firmware release.
