Is there a problem with alerts at the moment?

I set an alert for a flight the took off last night (still in the air) via the website.
The alert has has not appeared on the phone app.

I set the alert to send emails and to push to android, but nothing has been received.

Is it just me? Are alerts working for others?

edit:
Been playing to see what works.
Tried adding flights the the android app. All seems to go well, but after saving, no alert exists.

Got off a flight yesterday and I got (only) one push message, but no emails.

Adding Alerts to the app still doesn’t save anything.
