We have found one cause of the server issues this weekend. It seems the employee app jumped in download/usage by over 100% in a 24hr period causing an unexpected load on our servers. We are working to make an update to manage the loads better. Apologize for the inconvenience.
Over the last 2 days, push notifications and email alerts may have been slow to come or missed due to the previous server issues. Everything is running normally now. Sorry for the inconvenience.
