Why don't Facebook groups update the date they were last used?

[OLG4Life]

The list of Facebook groups that I am a member of used to update the date I last used the groups. Also the Facebook groups that I used most recently would be at the top of the groups list and the Facebook groups that I haven't used the longest would be at the bottom of the groups list. Facebook needs to fix the groups list so it shows the date the groups were last used? Facebook also needs to fix the groups list so the groups that were used most recently are at the top of the groups list and the groups that haven't been used the longest are at the bottom of the groups list?

Note: The group list that I am talking about is at: https://www.facebook.com/bookmarks/groups

Yes i have noticed this for the last two weeks, now i don't know if they have stopped the updates or it's just yet another bug,

Either way yes Facebook needs to address this issue but i wouldn't hold ya breath suckerberg has made his millions he doesn't care anymore nor did he in the first place!

Facebook has run it's course it's outdated and no support!
