If you can't see any booked meeting in your calendar you can try the following.
In your calendar you should be able to see any session that are booked, please make sure your Team on the left menu is fully selected (Check the boxes) or select the team members you are trying to see.
Please note you need to be an Administrator to be able to see you own availability and your Team availability as explained below.
This will display all the sessions booked and past bookings for each team member and they will be colour coded to that team member.
If after trying this you still can't see any booked meetings, it is time to check at client level the upcoming bookings.
1- Go to the Clients section on the top menu
2- Find the Client you booked (that is not showing in your Kara Connect Calendar)
3- Click on their name highlighted in blue or on the "eye icon" that appears when you hover over the name.
4- Inside the client profile you will be able to see the Sessions, past and upcoming.
