Hello
note sure its right forum, but since I am facing this issue when using PowerApps CDS, I publish it here
I was trying to give access to CDS to a user.
I found this access page, and click on Assign security role

my page is in chinese ???

I understand that this is being initialize when environemnt is first created. this the default environment, I have no idea who / how this was created.
anyway, when trying to access language setting, I have no other language option than chinese

When opening the other environment, language is in english and only english is available in the list
I read the trick to force language by using l=en-us in the url .. but does not work in this case
thank in advance for helping
