Shopify required, that we update our test environment, which we launched yesterday.
Then around 11 pm yesterday our servers had their daily review, and the new code did unfortunately not correspond with the required standards of the server review. This is why some of the pensopay merchants (only Shopify merchants) could've experienced some issues with the app in the late hours of yesterday and early hours this morning.
As of around 7:45 am this morning everything was back to normal.
