I have purchased the 200gb storage and it’s saying there is space free but it still won’t load my emails please help

I have purchase the 200gb storage plan for $4.99 a month as it was saying that my iCloud storage was full ... however when I have purchased this new plan it’s still saying it’s full when I log into iCloud.com , but my phone says I have only used 5.6gb of 200gb , it’s not loading any of my emails which are super important ... can anyone please help me ?

thanks
