- Open the Public directory in GSUI.
- Drag a file for upload into the directory.
The upload does not proceed (as expected). The network request log shows the error text and a status code of 403, but there is no feedback on the user on what happened.
Same happens on mounted external accounts with read-only permissions.
(Ted: I am assigning it you. Kick it back if you think it makes more sense I take it on.)
