Can you kindly provide the steps in order to reproduce this error?

This is an issue in the explorer, and we've de-prioritized fixes here to focus all of our energy on the toolchain:
https://github.com/carbon-language/carbon-lang/blob/trunk/proposals/p3532.md

We've tried to fix all of the documentation to reflect this change, but if we missed anything let us know (likely in a separate issue or on Discord) and we'll update there as well. Closing the issue for now.

@chandlerc You closed this as "not planned", but it looks like a duplicate of #3541. Note, that issue was fixed by #3544.
