There is no order button on checkout

Just a little information from testings. Using other version from woocommerce but want to test your new plugin. There is no “send order” button on checkout. But maybe I have the false credentials from Klarna. Do I must have to use V3-data to switch to this new version? I’m missing an important option in this plugin too. Option like a “fee” for using this payment gateway Klarna.

One more information about the latest update of the other plugin 2.5.8. (using this in production). Have to go back to version 2.5.7 because of an error in order status or communication with Klarna. Two orders has been accepted today by Klarna but both orders are going to “cancel/break” in backend because of a time out. I don’t see this orders in the logfile too. I have to switch the order on “processing” manually. I will wait for the next orders paid with Klarna to see if working again with 2.5.7.
