- If you install any of the recent builds from the Fast ring and switch to the Slow ring — optional content such as enabling developer mode will fail. You will have to remain in the Fast ring to add/install/enable optional content. This is because optional content will only install on builds approved for specific rings.
- As always, don’t install this on your production machine.
