I have Minecraft on PC and two android devices. A phone and a tablet. I want to upload a world from my tablet to my Realms. When I do this, it's exports my world, and when it starts to upload, or even before the upload, it pops up that there was an error. I repeat the process and it states that it failed to find a place to upload my world and to check my internet connection. This is all it does.
This has been an issue since April and it seems to be on Microsoft’s end, Someone from Mojang really needs to speak with someone from Microsoft about this.
