FC Lessons Advanced mission bug

I'm experiencing a Bug with the FC Lessons: Advanced mission. The 'login for 2 days mission’ never completes, I have  played for 1 month straight. I've tried clearing the cache and reinstalling FC Mobile a lot of times, but nothing works. I am playing from an IPhone 13 Pro Max and my UID is 671868205496471552

Just keep in mind that this little issue is pushing me not to play your game. Thank you
