I can only presume it is a problem at your end Paul, as all OK here.
To test first of all I set up local notifications and alerts on network flighta and was inundated with them so quickly changed to local aircraft to check they were OK. Set alerts to flight numbers I could see on the network coming my way. Also set to EC-*, 4CA*, 40*, VLG* ,RYR* etc and received local notification and email alerts for the first 12 I have picked up so far and have now turned them off as all is working as intended.
