v0 Design Mode edits not applying or persisting after clicking Apply

[sfallman-9089]

I, like most users, have experienced the ‘Design Mode is disabled’ error up until a couple of days ago (about March 17th, 2026).

Now that it is re-enabled, I’m able to select and see edits as they happen. However, I’m encountering an issue where changes don’t persist.

Steps to Reproduce

1. Make changes in Design Mode.
2. Press the Apply button.
3. The main chat runs the Design Mode Edit message.
4. The agent does not seem to have any context about the changes made.
5. Upon refresh, the edits are gone.

Current Behavior

As soon as I press Apply after making design mode changes - the main chat runs the Design Mode Edit message, but does not seem to have any context about the changes that were made. Upon refresh, I can see the edits that I instructed the chat to apply are gone again.

Is this a personal workflow issue or a bug?

Probably has the samething to do with all the other errors and such that are happening right now with their latest update. For those of us that use it daily, it feels completely broke.
