Hi ​@Natalina could you please share this info with your friends in case they are Non-Deezer users?
 

How to use Shaker as a non-Deezer user

If you are new to Shaker, and this is the first time you have been invited by a friend to collaborate on a Shaker group, you will need to complete the following steps:

1. Click the link received from your friend to join their Shaker group OR go to shaker.deezer.com
2. Follow the steps to create your Shaker profile
3. You will be asked to import your existing music library from another streaming platform. To do this, you will need to connect to the respective platform before the import can begin
4. Once the import has begun, it will complete in the background. In the meantime, you can enjoy the mix, discover sharable fun insights such as compatibility scores between you and your friends, as well as being able to invite more people to enjoy the Shaker experience!

Also, could you please share a screenshot of the error message they get while clicking on the invite link?
Thanks
