Mautic integration with suit crm 7.8.2

I am trying to connect Mautic with Sugarcrm 7.8.2. If I select the 6.x / community toggle (the 7.x option gives an error with an array) in Mautic the connection is working. Also I am able to map the fields. But unfortunaty the mapping is not saved.

Can anyone help me? I would very appreciate it!

I wouldn’t use the official plugin. There’s something much better introduced by eVolpe from Poland. More details here https://evolpe.com/suitecrm-mautic-integration/ Good luck @Dennisva
