Sometimes services on IFTTT run into issues like high error rates. To prevent Applets from being disconnected, services are paused automatically or by someone on the IFTTT team when an anomaly is detected.
A paused service does not perform trigger checks, so the Applets don't run the actions. The "Check Now" button is also disabled.
As soon as the service is unpaused the Applets will continue to work as expected.
Whether or not the Applets will pick up missed events when a service is unpaused depends on the nature of the underlying issue and the service itself.
