The problem you've described sounds like a temporary issue and should have been resolved now. Please try again, and email us at help.minecraft.net/hc/en-us/โฆ if you're still having the same problem. ^RL
The problem is not resolved. I'm having this issue right now trying to replace my realm world in ps4 :(
'Replace world' doesn't work and 'Play on Realms' doesn't work too
