incorrect_login on third party apps - Lemmy.world

Hello, I’m new to Lemmy and am trying to login to my account through an iOS app. This problem happens every time I try to log in using the correct details (copy and pasted from my password manager) on both Mlem and Memmy apps. Every time I try to log in I get an incorrect_login exception. I’ve tried using both lemmy.world and https://lemmy.world as the server. I have validated my email account by clicking the email and logging in, so I’m not sure what is causing this. Anyone have a similar issue?
