Expected behaviour

When I want to join a private tournament, inputting the correct password should let me in the tournament.

Actual behavior

After entering the correct tournament password in small cases as it should be, I got an "error" response.

How to reproduce

Log on to the website Lichess.org and join the tournament with the same password, when you have successfully joined, open the link again on the app and continue the tournament.
