Credit Card Removed After Recent App Update

Noticed this morning that my payment method had been wiped out in the app. Went to the webapp to double check, and saw that the payment method was listed, but when I went to "edit" it, it showed that it had been removed there as well. 

I'm assuming this must have been an update issue, as I did not remove the payment method myself (nor would I have wanted there to be an interruption of my monitoring service).
