We’re beginning to see services recover, and we’ll continue to monitor as our Engineers work to ensure the fix will completely resolve the issues.
We want to assure you that throughout this outage, physical card payments have not been affected and have processed as normal, despite a delay in being reflected within transactions.
Thank you for being patient with us, and we’ll return with another update here shortly.
