I've been having issues submitting a refund request for the last 48 hours. I get the "Our system is having trouble. Please try again or come back later" message every time. I've tried through the web page, through the app, on an incognito web page, with a different browser, logged in to my account, not logged in, and cleared my cookies. I successfully submitted two prior refund requests a week ago - is there a limit, lol? I've done a search but don't find this specific question asked/answered. Any thoughts appreciated.
