I've created a custom template for B2C Sign In User flow. I wanted to add instruction text on the top of the page in 2 languages, so I created 2 templates, uploaded them to folders in blob storage.
When I insert a link to the User flow it is working for separated languages, but once I add a wildcard value {Culture:RFC5646} (which is recommended on MS docs) it doesn't work.
Have you got any ideas or advices of how this needs to be done?
Just to add another issue to this: the language is custom.
Thanks!
I managed to find the answer.
Instead of {Culture:RFC5646} I've added {Culture:LanguageName} and it fixed the issue!
