Custom domain name does not support multiple languages

I set up a custom domain name (not «embed shop in website») via the advanced settings in my Spreadshop store . However, this option does not support international shops, as indicated by an error message when I tried to connect my domain name. For this to work, I had to disable the “Enable all languages” option in the settings. My store has a .ca domain name, and it is not international. However, as a Canadian store, I am legally required to offer a store in both of Canada’s official languages: English and French. Since I connected my domain name, the store can only be in French or English, not both, as was the case before setting up the custom domain name. I contacted the support team via email: they indicated they had escalated the issue to the second level, but I haven’t heard from them since April 29. This is a serious issue that needs to be addressed as it relates to legal compliance. Could someone please contact the development team to report the issue and find a solution? Thank you.
