I used the app to add over 20 events for two Tapo P100 plugs today.When I try to schedule another event for any day or time, I get an error message "Failed operation. Do it once more later." What's going on here? This problem warning shouldn't appear when I add as many scheduled events as I like to either plug. The P100 plugs, if there is a bug, are unusable for me and will have to be returned because they are not fit for heavy schedules.
