I’ve been snagged by this twice. I think this is what is happening : when you go to edit an alert that you’ve posted, the alert date shown in the edit screen is incremented by one automatically. If you just edit other information and save, unbeknownst to you, your alert just got kicked up to the next day. You need to reset the date before you save after editing. This could potentially trip up a lot of activators if they don’t double check the alert after saving.
I click on “edit” for my alert later today (3/04/2020), and the edit screen instantly pops up with 4/04/2020. It does this on Firefox, Chrome and Opera browsers (Win7Pro).
Hey Barry - you have to do a hard reload to get the updates. On Chrome on my Mac, it’s alt+click the reload button. On a PC I think it’s control+click the reload or control+F5.
