Same issue been trying for several hours to upload. only managed to get a skyblock pack to load on to it
1. using version 1.14.60
2. No error message apart from failed: An error occurred. file seams to export fine with the notifications on the top then the progress bar disappears then comes back at 100% then above error
3. Windows 10 Bedrock edition
4. No addons, textures or behaviours
5. world size is 34mb
6. Tried exporting the world and importing it. Renaming the file and exporting/importing it. Tried adding via the edit world/add to realms page and via the edit realms section. I can get a Skyblock level to upload and a new world (sometimes) but nothing else
Having a paid service go down/not work like this under a P1 issue with no notification from staff is disgraceful. Mojang owes us just a notice saying they're looking into this. They haven't done anything to this issue. I would expect this from a free service not a paid one.
