Mission bugs

I am stuck on the beginner mission “grind it out”

won’t let me progress any further and am stuck every time I do the challenge right it doesn’t register I’ve tried uninstalling the game and re installing, I’ve restarted my game about a million times to see if that would work but nothing has, this issue needs to be fixed asap due to the fact this is the only way u can progress if any devs could let me know what’s going on that would be appreciated
