Interval calendar - Garmin Connect

Hello, I’m not sure if I’m writing in the right place… I’ll give it a try.
Can someone help me solve this problem: on the Intervals calendar there are my workouts, which until the end of November I could automatically find on Garmin Connect as well.
Now I don’t see them anymore.
How can I solve this problem?
Thank you

Start by checking your Connection settings on the Intervals Settings page - Connections - Garmin.
If those look correct, try disconnecting and reconnecting.
