Larger world sizes don't upload to realms anymore

Hello, I have had this problem where I can't change out my realm worlds if the size is larger than 100mb. It's a problem because I have had a world on a realm that has grown in size but I wish to continue playing and updating this world. It's 1.7 gigs. I can't upload my other world of 800mb either. Service told me that it times out if upload takes more than 5 mins now. Yeah of course it will for larger worlds. Can you please patch it. It uploads but the old world doesn't reset. Please fix this issue thank you!
