I meant go to AENS > Make sure view with your active auctions + registered names are selected > tap + button in the lower right.
This should create a new auction for the name.
There is an issue with active auctions not being populated correctly in the view mentioned above. But I believe your auction does not exist currently at all.
I was able to create an auction for arjan.chain on the testnet. I see it in the list of auctions by character length (5), but not in my active auctions.
If you are able to initiate the auction you should see it in the list of auctions by character length (5).
@zkvonsnarkenstein.chain we fixed the bug related to the names not showing in active auctions in the profile view. If the name is currently not being auctioned, you can bid on it as I described above.
