I am from Switzerland and have a since long time a zoho Notebook Pro and want to share one of my  notebooks with another user. I created him an account. However when I want to share my notebook with him, it tells me that he is in another datacenter. What can I do? My account is in tne US datacenter. I opened him an account and this was created in the EU datacenter.  He is in the UK and has no data in his account.
