Panic Averted

Me: Double click Word file to open Word

MS: Hi, there's a problem with your Windows 365 subscription, please log into your MS account

Me: Aaargh!

Also me: It's due to renew about now, I bet payment won't have gone through since I changed my credit card

Also also me: Logs into my MS account

MS: We can't find your subscription, did you buy it with another account?

Me: Aiiieeee!!! WTF!!!!

Also me: Clicks Subscriptions

MS Account Subscriptions: Windows 365 Subscription : Past Due

Me : Seriously MS, when you say you can't find my subscription, did you not think of checking under Subscriptions?

One quick card payment later, panic averted, but that was a particularly weird error!
