Hi Miroslav,
I have to do this often, and there is one solution: send in a ticket with this request. There is no way to do it yourself :)
It is usually picked up and finished within a couple of hours.
Good luck!
EDIT: In your ticket be sure to provide the App ID and the correct full name of the company you want the app to be connected to
Hi Wieke,
Thanks for your reply. Honestly this one I would recommend to improve the frontend. There are some security and licence implications behind and as such I would totally recommend that a company can be canged by the customer more easily. There can be also situations where the app is developped maintained and upgraded by one company, and another company just needs to use and takes part on the project management. So far since tehre is no other way around I would go for the support ticket solution.
Regards Miroslav
