I know the pantheon community is not a support forum. But still, after talking with pantheon support I think I will give it a try. Maybe someone has some experience so far.
In WPML it is possible to use an domain per language. From my webhoster I pointed to different domains to pantheon and set up the domains in pantheon as well.
Everything fine so far but switching the languages by clicking on the flag on my english website always points me to the englisch site and I cannot return to the german domain anymore.
Anyone had the same or similar experience?
