Survey language issues.  When I added a French language translation to my survey I ran into the following issues. 

1. The survey does not default to a language, as the language checkbox on a contact record is not used in displaying a survey in a specific language.  My thought is 98% would default to English and other those with the checkbox would have to select French in my example.  Currently if you select a language, then it always prompts all users to pick a language.  
2. Language picker default language error, which my admin logged an issue on: https://trailblazer.salesforce.com/issues_view?id=a1p4V000001Yq19QAC.  Specifically, if you pick French the survey stays in French if you go back and try and select the English version.  .  
3. Once you add a language you can't remove the language.  You have to create a new (clone) the survey and use the new survey you just created.

Any insights or suggestions to these issues?
