Receiving on a 0 invoice doesn't show the amount received

[Sjors]

I just received some sats from a General Bytes ATM. The ATM requires a 0 amount invoice, because it decides the exchange rate for the bank notes that I feed it.

The app correctly showed that the invoice was paid, but it showed the amount as 0. The transaction history page also shows the amount as zero.

My Lightning iOs wallet has a channel to my c-lightning node, so I was able to check the c-lightning logs, which do show the correct balance change message.
