Checkout not working bug - transaction cancelled - checkout process not completing (prEvent, emv, internal error)

[mrgithub]

Running the example code. I think it's a wonderful plugin.

First time it worked and allowed me to touch the reader with phone (using developer credentials on the sumup_flutter app and changed the currency to 'GBP'). Thereafter it when button pressed to checkout it briefly flashes the screen to find the reader then goes to a page saying transaction failed and it was a network error.

I don't understand why it's not working. I've googled everywhere. The console shows this:

Event prEvent Checkout - Reason: Internal error E/SumUp ( 3450): (Source File:1)@main | Error for in emv response: Internal error

I'm also seeing the following:
Expecting binder but got null!

Hi, is it still happening? It may be a temporary SumUp server side error. Sometimes server side errors happen.

If it's still happening you can follow this SumUp issue.
