Our website offers three different languages. Each language has it own top level domain (example: domain.de, domain.it, domain.fr). Everything works like it should, except the Live Preview function. We have already tryed the things described here: https://craftcms.com/support/cross-domain-live-preview and a few other tweeks we found in stackoverflow. Every solution we found, only works with subdomains.
As i understand, it's not possible because the browser does not allow cookies accross domains (Cross-Domain Policy).
Does anyone have experience with handling various languages and top level domains in Craft CMS? How can we handle this requirement?
