That would indeed be really convenient to top-up from Bancontact.
Especially that since a few days/weeks, I can’t top-up from my Maestro debit card issued from my Belgian bank. I don’t really know what happened ; it was working just fine since I joined Revolut but stopped working a few days ago (no way to top-up with the linked card “Only latin characters” message error and no way to link a Maestro card anymore).
For reference, I’ve posted this “error” here: I can't top up my revolut - #20 by jbelien
