Wikiloc App for Garmin Connect IQ

I'm Andrea a new Garmin client, I bought Montana 700 device. 
I have premium Wikiloc account since 2020.
I have a problem with Wikiloc App for Garmin Connect IQ. I have all requirements and latest updates: - Software Version: 13.10 - Software GPS version: 2.81 - Wikiloc version 2.3.6 and Premium account I associated my Premium Wikiloc account with my Garmin account.
So, I istalled Garmin Express on my Mac and I istalled Wikiloc Trails with it on my Garmin device.
However, when I enter in Connect IQ on my Garmin device and I click on Wikiloc app, it don't start.
Appear at the center of Garmin screen the Connect IQ icon with yellow esclamation point and nothing else. Can you help me to solve this problem? Thank you in advance, Andrea
