World export error

Hello, I want to report a very annoying bug, namely an error when I want to export the world into realms. even though I have a stable internet network, but always error or fail. and also the notification does not match what is happening, for example I export my world into realms. the notification says that the world has been exported successfully, but the notification exports error or fails, and it happens repeatedly, so I want Mojang to fix this bug that has not been fixed for a long time, because I'm not the only one who feels this, ( maybe) everyone feels this way. that's all I can say, I really hope that this bug can be fixed as soon as possible, With that I say THANK YOU , Warm regards DoodleGG
