I have been having a problem with giving thumbs up not showing as given later. On some threads I read, I just mark everyone with a thumbs up. I have been noticing for quite some time when I go back at a later date the thumbs up are not showing so I regive them. I do not know what occurs on their end, if they are getting them or if they are taken away. At first it seemed like it happened more if I was posting a reply at that time. Hit some thumbs up and post a reply. Now I do not know and it seems worse. But then I also wondered about my Android tablet. The NGA site has navigation buttons and action buttons to use. But my tablet has some of them, too. Especially a different back button. Then in addition tablet added 4 shortcuts in the site. So if I give thumbs up and I am done. I can use NGA to navigate such as back to home page or profile. Or I can use my tablet for back, and other shortcuts, which are homepage, profile, daylily search, and my Caffeinated thread. So I think the thumbs are dropping off because of the way I do navigating? If it was the site wouldn't more people say hey I think I am crazy. I am giving thumbs up and when returning to the thread they do not show. Any ideas?
I did have a thread reply duplicate yesterday for the first time, but I think it was my tablet's back button. It occurred while using my tablet navigation not the sites.
And on certain posts I have accidentally given myself thumbs but go back and remove. Does not occur on every post just randomly and I thought we could not ever give ourselves thumbs.

and May you and your family receive an overabundance of blessings!
