Today I got an Update to Minecraft I tried uploading the world it took much longer and gave some promising but at the end still gave me the same "An error has occurred"
HOWEVER, the world did actually upload to the server from my switch successfully and was not only downloadable at its full size on my PC and Switch but was on the realms server successfully
My error could have been pure chance!
Thanks Team
I've also noticed this it's really quite a quiet game on the switch despite max volume
I'm on Switch just did the 30 Day Realms trial super pumped to play with my GF and friends on Minecraft for the first time in a long time on our little server but only to also find I can't upload a world from my Switch and it just says "an error occurred" However PC uploads without a problem
V1.16, Switch & PC
I've tried the following with no fix
Tried another world
The world is only 15mb
No resource packs
Renaming the realms server
Renaming the world it'self
Restarting the game
Restarting the Switch
Twiddling the thumbsticks
Trying over and over again
I've tried the following with results of sorts
PC works and uploads worlds
What I will try
Getting a USB C to Ethernet adapter for the switch
Changing Wifi
Hoping to extend my trial on the missed days of play
My only suggestion as others have said is to keep trying to upload the world, However every time it errors go onto the realm and try and download the world onto your console or device and hopefully eventually despite it still gave you "An error has occurred" you will actually download the full world at the correct size, 9/10 times it will only upload the seed number but I think sometimes it will actually upload the whole world on very rare occasions.
With the 16.1 updates, I thought it was fixed because mine worked the first time despite still getting the "An error has occurred" but it seems everyone still has issues. Now my World is finally on the realm I will continue to use my PC version of Bedrock for any further realm changes as a don't trust any other version.
So Disappointed at Mojang to see this is still a persistent issue on and off for what seems like months? Voices on here feel really unheard.
People are losing a lot of fun with friends and time on a paid service.
I'm loving this Realms service right now as it's working for me If I get any of the rollback issues people are mentioning I'm out and I'm not coming back, I'm lucky as I am now being able to have actually uploaded my world which was nearly impossible and also could have essentially ruined the service entirely for me
