Yeah, I'm not using anything extra.
Glad I'm not the only one who is experiencing this. I mean, obviously I couldn't have something different than everybody else but this means that I didn't just screw something up in the settings. I haven't tried mobile in a long while, but I would imagine it's experiencing the same issues. I know Mojang develops this, but I hope Minecraft doesn't become another Microsoft product that they screw up because they're too focused on features rather than functionality.
Recently ran into this error when my friend was trying to change a texture pack on his Realms Plus subscription (which he is PAYING for). I'm utterly confused as to why this issue hasn't been resolved. This is a completely game breaking bug that's existed for 2 whole years and Mojang hasn't even looked at it? Quite ridiculous. I understand game development is incredibly busy work, but to neglect something this game breaking, and by the way, revenue killing, is foolish and lazy.
