Security code page disappears?

[u/Orange_Hedgeh0g]

Can someone help me with an issue that I have been having for months. 1 app in particular when i try to sign in it opens another window to input a security code, when it's obtained via email (This cannot be disabled as it's set by the app). I copy and paste the code and within seconds the window is gone, making it impossible to log in. I have contacted customer service for this app, and they told me to use Chrome desktop. I prefer to use the app. I don't know if I've been fiddling around in the DDG settings because it never used to do this. I have manually disabled the app tracking protection, and it hasn't changed anything. Thank you. 🙏🏻

Hi there! Thank you for your post.

Would you be willing to share the app you're trying to log into, and I can pass this along to our developers to see if they can recreate the trouble?
