Unity GameCenter Leaderboard issue

Hey, i have created a game in unity with the apple core and apple gamekit plugins present. I setup 5 leaderboards on the app store connect. I made a unity build and did the whole testflight build loop to test everything. When i open my gamecenter panel via the button i see my leaderboards but they show as MISSING TITLE which is weird because i have for sure set them up correctly they have a leaderboard reference name and leaderboard id as well. When debugging i can see that when i call my submit score function it gets submitted with no error but then i also dont see the score appear anywhere .

Keep in mind the leaderboards are not live and are being tested on testflight first

Check if you filled Leaderboard localization

Hi, In my app it works without localisation. I setup the default language English only for the leaderboard and the title is displayed correctly when the app is started on an iPhone with system language set to German. Chris
