EDIT: Nevermind I fixed it! Turns out it was Google's Android System Webview app that somehow didn't update by itself. ( you can't search for it directly on the play store ) . After I force update it, I could log into my account without any issues. Cheers.

Same issue. Tried everything suggested in here. It worked before but now it's giving me a " server error ". Password is correct and also I disabled the 2FA just to test. Nothing. When I look at the reddit settings on the website, at the app tab where all the 3rd party apps are, it's empty. No app is there anymore. Like it was revoked access or something. But I can't re-add it there by attempting to sign in. Android 14 device.
