LNURL-auth works with any wallet since LNURL-auth actually has nothing to do with the bitcoin network.
thanks for testing! :)
btw, you can also see if a LN invoice is on mainnet or not by looking at the prefix. mainnet invoices start with lnbc but this one starts with lntbs which is signet. just fyi :)
