QA Notes

Get a CJIT channel, check the "You will receive" amount matches the actual amount received, check that the receive capacity is not at the maximum

[coreyphillips]

Receiving the following errors when attempting to create a CJIT invoice. The "You Will Receive" amount seems to exceed the specified amount. Tapping "Continue" results in "Failed to create cjit entry".

Yeah that is because the MINIMUM_AMOUNT is not dynamic yet. Needs to be fixed but not in the scope of this PR. For now you have to put in something larger like 200 000 on staging.

bitkit/src/screens/Wallets/Receive/ReceiveAmount.tsx

Lines 27 to 29 in c55c045

	// hardcoded to be above fee (1092)
	// TODO: fee is dynamic so this should be fetched from the API
	const MINIMUM_AMOUNT = 20000;
