I just paid my AMF for the period 1 October 2019 to 30 September 2020. When I was redirected to the (ISC)² member home page, the home page still said I owed $125, even after I just paid it.
I thought this was unusual, so I reloaded the page, same thing. Then I hit Ctrl as I reloaded the page to force a new version from the server instead of reloading the cache. Same thing, still said I owed $125 even though I just paid. Finally I logged back out and logged in again, with the same result, it says I owe $125.
The $125 posted to my credit card, but I don't trust that it's been properly reflected in (ISC)²'s records.
