So basically you have to enable developer mode to show & install the app? Or are there additional steps that you need to do before installing the app? Kinda weird they don't explain this in the official guide. Since migration is necessary for NEO holders I don't know why it needs to be gated behind a developer mode either, CMIIW. Glad to see you work it out OP.
Yes, exactly.
After a long wait, Ledger Support informed me of this.
As soon as you switch on developer mode, the neo app will be visible in the catalogue.
