Hello,
I know there are other topics with the same subject but any of the proposed solutions works for me.
I create a solution with 2 apps because there are very similar but in different language and use the same SharePoint site.
The one for dutch users works perfectly but I cannot execute the one for french users.
I've tried to clear cache, disable pop-up blocker and allow cookies for Power App site, ... The error still remains.
Also, I'm wondering about using one solution for 2 apps. So I try to put the app in a alone solution and redefine the environment variables and the result is always the same.
I'm tearing my hairs out on it since yesterday and have no idea. Could you please help me?
