I have noticed that, for group notices, there are 3 different character limits in the 3 different places it displays.
  1. Where you write the notice.
  2. Where it displays in the group profile.
  3. Where it displays in the notification pop up.
It would be much better if they all had the same max character limit so you couldn't type more than it displays in the group profile and pop up and, hence, never cuts off.
I am using Firestorm like many people so if this is an Firestorm issue, please let me know and I will direct it to them.
