I just accidentally did a double-submit after using ‘Add new edition’ on an existing work, because I got a blank page after submitting the Add New Work form instead of what I’m used to. Unfortunately, I’d left the page before I realised what happened so I can't give more detail. I'm not sure if this lack of feedback after submitting is related to the new automatic 'Add new work' functionality.
I edited the work page* to remove the duplicate entry (#31403), leaving the first attempt (#31402). I don't know if there is anything else to remove to clean up.
Add new work: double-submit
Re: Add new work: double-submit
No major problem. When the automatic procedure is used, the contributor should also finalize the composer page, as described here, step 6. I did it.
