my mozilla vpn isn't working. Been using it fine for a year or so. Got a new debit card. I think that was the start of the problem. Said it couldn't find my account, however I can log onto firefox fine in the web browser. the vpn app redirects me to a web page to pick out my plan, i click on a plan and i get the error "problem loading invoice preview". Been like that for a few days. so I am unable to add my payment information. the web page showing the error's address starts as "https://subscriptions.firefox.com/products/prod_FvnsFHIfezy3ZI?device_id" I have tried loading it in both the firefox browser and the brave browser. I believe i am windows 10.
