Android App Beta Languages and Trouble Logging in

I learned a ton years ago studying Spanish with LingQ so I thought I’d subscribe again to brush up on my Spanish and start learning Latin. I just downloaded the Android app and I couldn’t login with my username so I had to use my Google account to login. That seems like a bug. More importantly, I don’t see where to select Latin in the Android app, and I don’t see the private imported Latin lesson I uploaded with the web app anywhere in the Android app. Does the Android app not support Beta languages?

That’s strange, I just checked and I was able to login into Android app with my Username/Password without any problem. Can you please try again? Note that both username and password are case-sensitive.
Beta languages don’t appear on the app initially. However, if you open a beta language on the website it will automatically appear on the app too.
