Cannot send Bitcoin Cash: 500 - “min relay fee not met (code 66)”

[Igetin]

Description

When trying to send Bitcoin Cash, the app shows the following error:

500 - “min relay fee not met (code 66)”

I am not sure what the relay fee refers to or if it’s something I am able to change in the app.
The payment confirmation screen shows “miner fee”, which seemingly cannot be changed.
The miner fee section shows “NORMAL” with the sum 0.000001 BCH. Below that, it says
“0.00 EUR (0.00% of total amount)”.
