AppStoreConnect - app name still unavailable after 2 days since it became free

So we had an unreleased app in one account, and decided to rename an existing app in another account using its name. I renamed the app in the first account so that name becomes free, and then deleted it altogether. However I still get this error (2 days have passed) when trying to set a new app name (which is already free):

English (U.S.) Name couldn’t be saved because the app name you entered is already being used. If you have trademark rights to this name and would like it released for your use, submit a claim.

New name in other localizations in successfully saved, but not in default language. Any workaround to this? Or the name is still cached and we need to wait some more?

Message is very clear. As the app did exist in AppStore, there would be a risk of confusion.

So provide the requested information to the reviewer, proving that you are the legal owner of the app name. Workaround of course is to have a slightly different name.
