Version Of Tizen

I’m actually developping a web application on tizen for a samsung signage.
I’m trying to use FileSystem object with web api and can’t use the new version. I’m blocked with the deprecated file system. If someone know how to switch to tizen 5.5 on my application. It would be grateful.
I already tried to change version on the config.xml, tizen then required version to 5.5 but nothing is changing when I build.
Thx for your help.

I’d recommend you ask for help from the Smart TV Seller Office 1:1 support.
