Ok  @Alby is it in the LND side or the albyhub side that fails to decode an invoice without an explicit sats amount?

I would love that if it's something you guys can implement. 🙏 
(I can't send to CashApp otherwise)

 Lnd can decode them 

 You can add amounts to Cash App invoices by clicking the up and down arrow button under the price chart.
