More from Josephus (nprofile…5jps) after filing, which changes the picture a little: the answer they picked was **"A previous install, or a phone I no longer have"**, so the walk ran the clean-up — but the other holder is live. It is the Cordn app on the *same phone*, signed in to the same account. Their words: "half-true… the keys the error was referring to were on the same cell phone, but on the Cordn app rather than Staircase."
Two things follow:
- The sweep withdrew a running client's key packages. Nothing is committed, so both apps keep their chats, but that client will publish a fresh key package and the finding — and the hold — come straight back. That is a second route into the loop this issue is about, and it needs no unreachable coordinator at all.
- The question's three answers are read against "another *device*". For a second app on the phone in your hand, "a previous install, or a phone I no longer have" is the easy one to pick and the wrong one; "Yes, and I still use it" (link) is the answer that settles it. Worth a word on that step naming apps on this phone as well as other devices.
