Hi
Last week I won the steps weekly challenge (80K).
In garmin support web pages (https://support.garmin.com/en-IE/?faq=fU0T2AppaJ68D0sQEdlDK7) you can read:
Understanding Step Challenges in Garmin Connect
If you have a device that tracks steps, you can participate in challenges with other Garmin Connect users. Each week a new challenge begins during the night between Sunday midnight and Monday noon (your own time zone). As your steps add up throughout the week, you’ll see your rank with the other 7-12 participants in your challenge group. If you win a challenge, you’ll earn a badge.
After three days waiting for the final challenge analysis since challenge end, i didn't achieve any badge.
This is the ordinary garmin challenge behavior?
