when I press button "get started" after login: https://www.minecraft.net/login?view=mojang&ref=launcher
when I press button "migrate now" in your email: https://www.minecraft.net/mojang-account-move
Just would like to add it is going on Bedrock Edition 1.10.0, iOS platform.
I don't understand your request - what should I update ...
Anyway, the issue still exists, nothing has helped (consulted with the Community Support). My son can't play Minecraft anymore - not able to download 1.12.2 (Minecraft Launcher 2.0.1004). MacOS.
"This issue is usually caused by adblockers, uninstall any adblockers you are using, restart your mac and try again."
But I don't use any adblocker.
The same issue occurred when I launched 1.12 version ... that time I did not use any adblock, either.
We find out that in the installation instructions you write about .mcpacks but both files are .packs ... could be this the reason why it does not work?
I have already found a way how to migrate so it is not valid anymore.
