Wrong amount read from LNURL withdraw

[TKone7]

Hey there,

We are providing LNURL withdraw to our customers to claim their sats that they bought with Pocket.

In the latest version (2.0.0) of the Phoenix beta app we experience issues with certain amounts.

With the below LNURL we offer to withdraw exactly 1'113'244 sats. However, Phoenix interprets the amount wrong and creates an invoice of 1'113'244'032 msats. This in turn is validated on our end and rejected because the amounts mismatch. This then prevents the user from withdrawing his funds.

Note: Feel free to test with the below LNURL. It expects a testnet invoice. But you won't be able to claim the funds even with a correct invoice because we restrict to wich pubkey it can be paid out. But for testing it should suffice.
