Scolling jumps on personal board

when I get to my own board, open it up and start to scroll down to find a certain pin I pinned say 2 weeks ago, I cannot for the life of me get to it because it doesn't scroll anywhere past 10-15 pins and and it takes you right back to the top (the first pins at the top of the board)
I am just really frustrated. My Pinterest app works on my phone but the Pinterest site on my desktop, on my computer, in Safari and in Chrome, DOES NOT WORK properly at all.
