Apple Arcade game Patterned is not updating the Leaderboard Daily Play Streak recently

I have a 5th generation iPad running IOS 18.7.1, but I do not think my problem is specific to the iPad. Playing Apple Arcade's game Patterned, the Leaderboards "Daily Play Streak" has not been updated for approximately 3 weeks, even though the "Current daily streak" that is displayed on the Patterned home page has continued to be updated.
