Embedded browser login causes issues in Android app

I'm unable to easily log in to the app due to the following issues: When logging in with Facebook, it returns an error because they do not support embedded browsers. Apparently this hasn't been supported since 2021 When trying to login to the Trolley app with Google, Microsoft or Twitter, despite already being logged into those in both apps and Chrome web browser (which the app could utilise), the app prompts me to login to these again because it's using outdated embedded browser technology. As my passwords are saved in my password manager and auto-fill can't be used in embedded browsers, it's very difficult to login.
