I have 5 alerts set up. All 5 of them were to send updates to my mobile phone *and *to my email address.
A few days ago, I noticed that a couple of the alerts were only going to my cell phone - but not to my email.
So I went in and looked at the alerts and the email address had been un-checked.
The problem is that when I check re-checked them, I received an error message stating "You cannot have more than 5 enabled flight alerts, sorry."
But there are only 5 !!
