You are receiving them but as CCs - most likely because the amounts are too small to justify routing them as sats across the network.

For zaps here, there’s no avoiding wrapping and this failure for small amounts without a direct channel.

But, if you want to just use the SN Lightning address and don’t need the privacy of wrapping, uncheck ‘proxy invoices’ in your settings. It’ll return an invoice that routes directly to your node then.
