Why do I get the error- "Token not refreshed: payments2UsBillingFetchQueueable "?
This error is pointing to the Billing area of Payments2us where you can get copies of your receipts, update your card and contact details with us.
To solve this error-
Please Go to Setup ->Search "Remote Site Settings". Then locate "AAkonsult" and make sure it is active.
Also, stop/restart the Batch Processor. See FAQ 1 of https://help.payments2us.com/m/userguide/l/1194277-batch-processor-faq
If the Remote site "AAkonsult" is not there on the list, then please add the Remote site with the Remote Site URL - "https://aakonsult.my.salesforce.com" and Activate it.
