Ark server is a setting again; an address on another server falls back to Lightning.

Settings → Advanced → Ark server: coinos, Second (ark.second.tech) or a
custom server, per network — the stored choice is honoured on mainnet
again. Ark state is kept per server, so switching hides but never loses
coins; the card says what the current server holds and asks before letting
go. After a switch the reusable address, the nostr advert and the payment
name's ark= instruction follow the new server.

Sends between servers can't be arkoor, so an Ark address that names a
different server (its first bytes hash the server key) is treated as no
Ark address at all in the pay ladder — a coinos name or npub then goes
over Lightning by itself — and a pasted one is refused with the reason.
