I’m sorry you’re having trouble with this. No worries, we'll check this out. When did it start happening? Has anything changed in your environment? Is the Airplane or Do Not Disturb mode turned off or on? Did you not receive any push or email notifications? Also, have you checked your spam folder?
It's me again. Just wanted to jump in here to make sure that you saw our response. Please let us know if you have any other questions or concerns as I will be locking this in 24 hours.
