This latest stupidity by AARP just started around 2:35AM Pacific Time, Monday 11/16/2020.
All of a sudden, in the middle of watching videos and taking quizzes which were just crediting points a few minutes before, the crediting of points just stopped. Also, completed activities stopped showing as "checked off" on the list of activities, and ceased being shown in the transaction history, both at the same time as points stopped being credited.
Somebody on AARP's "IT Team" or whatever they're calling themselves touched something they weren't supposed to, or tried to change/upgrade/fix/enhance/etc etc etc something that wasn't necessary, and fouled up the website for about the millionth time. All it takes is changing/deleting/adding one character on one tiny piece of coding to mess everything up.
SUGGESTION TO AARP "Techs": Keep your **bleep** hands off the **bleep** website when there is no reason to be poking around the coding/scripting, you are only screwing things up more than they already are!!
