Just checked and I have it activated already. Must be the setting which hides username when sending, since that's to my knowledge only thing I modified in it, and that was a long time ago.

I still have a small bone to pick in that if I find say a Foutain podcast wallet with it, the receipt includes a note like "fountain user12345" and I can't remove it. Not great, as I assume Strike could then theoretically connect identity to nostr handle, if they wanted to, or worse accidentally leak that info in the future (everyone leaking data these days afterall), and possibly dox my nostr history :(
