Platform Notifications signature mismatch since last Friday night
Hi, all of our platform notifications that we receive since last Friday (2019-09-27 ~1600 UTC) are failing our signature checks. We have not changed anything on our end for 4 years now, but for all of our customers signature checks were failing as of that night. (Some earlier, some later) Can you please check your recent deploys and give an update? Thanks in advance!
